5 essential things to know about mesothelioma cancer

A rare and aggressive form of cancer, mesothelioma cancer affects the mesothelium. This is the membrane that lines the insides of internal organs in the body such as the heart, abdomen, and lungs. Caused by exposure to asbestos, mesothelioma cancer usually starts in the chest cavity. This happens in nearly three out of four cases. In some instances, cancer can also start around the heart and the abdominal cavity.

5 essential things to know about mesothelioma cancer

Based on the part of the mesothelium affected, mesothelioma cancer is divided into different types. The cases in which the membrane and tissues of the lungs are affected are classified as pleural mesothelioma. The rarer types affect the heart (pericardial mesothelioma), abdomen (peritoneal mesothelioma), and sometimes the testes (testicular mesothelioma).

Probable causes of mesothelioma cancer

  • Exposure to asbestos
    One of the major causes of mesothelioma cancer is exposure to asbestos. This is why a majority of the mesothelioma patients are those whose jobs involve continuous and prolonged exposure to materials containing asbestos. A person in these job settings ends up inhaling or swallowing asbestos fibers without realizing it.
    Made of a group of minerals with microscopic fibers, asbestos can become embedded in the mesothelium once it goes into the body. This leads to internal inflammation and causes damage to the tissues in the lungs, abdomen, and heart leading to cancerous tumors.
  • Exposure to zeolites
    Chemically associated with asbestos, zeolites are usually found in minerals known as erionite. This mineral is commonly found in the soil of certain regions in Turkey. According to the American Cancer Society, exposure to zeolites and erionite has led to higher rates of mesothelioma cancer in these regions.
  • SV40 virus
    According to the American Cancer Society, the risk of mesothelioma cancer may increase due to infection caused by simian virus 40 (SV40). A number of injectable polio vaccines administered between 1955 and 1963 were reportedly contaminated with the SV40 virus due to which nearly 30 million people in the country were exposed to this virus. However, studies have not produced many substantial results that associate the SV40 virus with mesothelioma cancer.
  • Radiation
    Exposure to high doses of radiation to the abdomen or chest may also increase the risk of mesothelioma cancer. Additionally, mesothelioma can develop after the administration of injections of Thorotrast or thorium dioxide, a material that was used by doctors in certain chest X-rays until 1960.
  • Genetics
    In some cases, genetics may also play a role in increasing the risk of mesothelioma cancer. Some people may inherit genes that make them predisposed to this type of cancer.

Symptoms
Mesothelioma cancer is rarely diagnosed in the early stages. The early signs and symptoms are often similar to those of other conditions. Also, the symptoms change as the disease progresses. However, there are certain signs and symptoms that may help in determining the type of mesothelioma cancer.

  • Pleural mesothelioma: The common symptoms of pleural mesothelioma include chest pain, painful coughing, shortness of breath, unusual tissue lumps under the skin on the chest, and unexplained weight loss.
  • Peritoneal mesothelioma
    Commonly observed signs and symptoms of peritoneal mesothelioma include abdominal pain, nausea, abdominal swelling, fluid buildup, decreased appetite, fatigue, indigestion, and unexplained weight loss.
  • Pericardial mesothelioma
    This type of mesothelioma can cause breathing troubles, shortness of breath, chest pains, fatigue, fever, and heart murmurs.
  • Testicular mesothelioma
    One of the rarest form of mesothelioma, the most observed symptoms of testicular mesothelioma is the buildup of fluid between the mesothelium layer in the scrotum. A lump may form under the skin on either or both the testicles.

Stages
Mesothelioma cancer has four stages. These stages help doctors to classify and identify the progression and severity of the disease at the time of diagnosis.

  • Stage 1
    In this stage of mesothelioma, the tumor is localized around the mesothelial membrane and has not yet spread.
  • Stage 2
    Metastasis occurs at this stage. The cancer spreads to the nearby organs, such as the diaphragm.
  • Stage 3
    By this stage, the cancer cells have reached the nearby tissues, organs, and lymph nodes.
  • Stage 4
    This is the advanced stage of mesothelioma cancer where cancer spreads to nearby as well as distant organs, lymph nodes, and tissues.

Treatment options and life expectancy
Regardless of the type, mesothelioma cancer is not curable. Treatments and life expectancy depend on the stage of cancer.

  • Stage 1
    In this stage aggressive treatments such as surgery to remove fluids and tissues, radiation therapy, chemotherapy, immunotherapy, and targeted therapy are recommended. The average life expectancy is 21 months or longer.
  • Stage 2
    Treatment options at this stage are the same as those used in the first stage. The average life expectancy is 19 months or less.
  • Stage 3
    By this stage, the treatment options become limited. Treatments are recommended to alleviate the effects of symptoms and allow the patient to live as normally as possible. Life expectancy during this stage is about 16 months.
  • Stage 4
    Similar to stage 3, treatment options are mostly focused on hospice care and to lower the discomfort caused by the symptoms. The average life expectancy is about a year.

Best foods to have
Although mesothelioma is not curable, there are certain ways to help manage the disease. This includes eating a balanced healthy diet. Those undergoing treatments are often recommended to eat the following foods:

  • Fish rich in omega-3 fats
  • Fiber-rich foods
  • Spices such as turmeric, basil, mint, and rosemary
  • Natural sources of Coenzyme Q
  • Teas including green tea, herbal teas, and medicinal teas

An Overview Of Colon Polyps

An Overview Of Colon Polyps

An overview of colon polyps Colon polyps are small clumps of cells formed on the lining of the colon. The majority of these polyps tend to be harmless, but with time, there are certain polyps that can easily grow into colon cancer. This is a serious condition, especially when found in the later stages. Almost any individual can develop colon polyps. People who are over 50 years of age are at an increased risk of suffering from this condition. Even smokers and overweight individuals or people with a family or personal history of colon polyps might be at an increased risk of suffering from this condition. Colon polyps – causes are slightly known, but this condition rarely causes any symptoms. Therefore, for individuals who are at risk of developing the condition, it is important to have screening tests on a regular basis. These will include a colonoscopy. Polyps found in the early stages can conveniently be removed. They can be removed completely in a very safe manner. Regular screening is the best step for the prevention of colon polyps. What are the colon polyps – causes? Doctors do not exactly know the causes of colon polyps, but they are of the view that polyps are a result of abnormal tissue growth. The human body develops healthy cells in a periodic manner, thus replacing the old cells that tend to be damaged or are no longer required. The division and growth of these new cells is regulated. However, there are cases when the new cells develop and then divide before they are actually needed. It is this excessive growth that results in polyps. Packaged red meat is also one of the most common colon polyps – causes. Fiber deficiency in the body. High-fat diet taken in excessive amounts. Smoking cigarettes. Obesity is also one of the major colon polyps – causes. Inherited conditions such as Gardener syndrome, familial adenomatous polyposis, and Peutz-Jeghers syndrome might also put an individual at an increased risk of having colon polyps. What signs and symptoms do colon polyps show? Majority of the individuals suffering from colon polyps do not show any symptoms. They are actually unaware of the fact that they have polyps, because they feel very well. Bleeding from the rectum is one of the most common symptoms of colon polyps. Blood in the stool can also be a sign of colon polyps. Blood might make stool look black, or there can be red streaks in stool. A feeling of tiredness due to anemia and not having sufficient iron in the body are common symptoms. It is the bleeding from the polyps that can result in an iron deficiency and anemia. Several other health issues might also result in these signs. Nevertheless, if rectum bleeding or blood in the stool are everyday phenomena, a consultation with a doctor is vital. How can colon polyps be prevented? Knowing the colon polyps – causes can help prevent the condition. However, there are other important steps that can be followed in trying to prevent this condition. They are as listed: Regular screenings. Lifestyle changes can also be of help in doing away with the colon polyps – causes, and, consequently, prevent them. Adopting healthy habits such as eating fruits, whole grains, and vegetables and reducing fat intake can help in the prevention of colon polyps. Limiting the intake of alcohol and quitting tobacco. Staying active physically and maintaining a healthy body weight is also important. When should one see a doctor? A general physician must be consulted in case of the following: Blood in the stool Abdominal pain Changes in bowel habits for more than a week It is important for one to have a word with their physician regarding their intake of vitamin D and calcium. This is because studies have proved that increasing the intake of food items rich in vitamin D and calcium can help prevent the recurrence of polyps. However, this is not completely clear. It is important to consider all the options, especially if one is at a very high risk of suffering from colon polyps.

The Types Of Colon Polyps And Their Prevention

The Types Of Colon Polyps And Their Prevention

The types of colon polyps and their prevention Growths that occur on the inner lining of the colon (large intestine) and usually protrude into the colon are known as colon polyps. They form when the genetic material within the cells that line the colon changes and becomes abnormal. Under normal circumstances, the immature cells that line the colon multiply, mature, and then die in a timely fashion. On the other hand, the genetic changes in the lining cells prevent the cells from maturing, and they don’t die. Resultantly, immature and genetically abnormal cells start accumulating in the colon, eventually resulting in the formation of polyps. This article intends to raise awareness about colon polyps, its types, symptoms, diagnosis, the colon polyps – causes, and more. What are the types of colon polyps? Inflammatory colon polyps : Also known as false polyps, it is mostly found in people who have inflammatory bowel diseases (IBD), such as Crohn’s disease or ulcerative colitis. These polyps are inflammatory manifestations of IBD, are benign, and are unlikely to become cancerous. Adenomatous colon polyps : Also known as adenomas, this type of colon polyps make up about 70% of all polyps found in the colon. They can become cancerous, but the process takes years. Hyperplastic colon polyps : The term hyperplasia means fast growth, which indicates an abnormal increase in the number of cells resulting in the gross enlargement of the colon polyp. Despite the rapid growth, hyperplastic polyps have a low risk of turning cancerous. Villous adenoma : This type of colon polyp has a greater potential of becoming cancerous. It is estimated that approximately 30 percent of villous adenomas develop into a malignancy. These polyps require surgery for the removal of their cauliflower-like protrusions. What are the causes of colon polyps? Experts are not sure about the colon polyps – causes. However, the causes are believed to be a mix of environmental and genetic factors that result in an abnormal tissue growth. What are the known risk factors of colon polyps? Age : The risk of developing colon polyps tends to increase with age. Family history : A close relative with colon cancer or polyps raises the risk. Sex : Men have a slightly higher chance of developing polyps. Race : Black men and women have a higher risk. Alcohol : Alcohol consumption is closely linked to colon cancer risk and is known as one of the colon polyps – causes. Red meat : If not had in moderation, red meat can serve as one of the colon polyps – causes. Having too much red meat increases the risk of colorectal cancer as well. Lack of dietary fiber : A good intake of fiber has many benefits, including colon benefits. It decreases the risk of colon cancer. Smoking : Smoking increases the risk of all types of cancers, and colon polyps or cancer is no exception. Obesity : Obese people are at higher risk of developing colon polyps and cancer. How are colonic polyps diagnosed? The following tests help diagnose colon polyps: Colonoscopy Sigmoidoscopy Barium enema CT colonography Stool test What are the symptoms of colon polyps? Change in stool color Rectal bleeding Iron deficiency Anemia Change in bowel habits Abdominal pain Blood in the stool Fatigue How common are colon polyps? They are very common. They increase in prevalence as people age. If one has colon polyps, they are more likely to develop polyps elsewhere in the colon later. Only a small proportion of polyps cause symptoms or signs, which usually are the result of bleeding from the polyp. How can colon polyps be prevented? Adopt healthy habits : Adopt healthy habits and increase the intake of fruits, vegetables, and whole grains. Limit fat intake, alcohol consumption, and quit tobacco. Stay physically active and maintain a healthy weight. Avoid all the estimated colon polyps – causes. Seek advice if at high risk : If there’s a family history of colon polyps or its other risk factors affect one, seeking prompt medical advice and counseling is important. With regular colonoscopies, one can prevent the colon polyps – causes from developing, and hence preventing the colon from developing.

Carcinoid Neuroendocrine Tumors – Prognosis And Life Expectancy

Carcinoid Neuroendocrine Tumors – Prognosis And Life Expectancy

Carcinoid neuroendocrine tumors – Prognosis and life expectancy The neuroendocrine system is a complex regulatory mechanism comprised of cells spread throughout several organ systems, including our lungs and digestive system. As they have characteristics of both nerves and endocrine cells, they are called neuroendocrine cells. The nerve cells transmit signals using electrical impulses, whereas endocrine cells make thyroid and insulin-secreting glands. This article intends to discuss the carcinoid neuroendocrine tumor that starts in these cells in detail. What is a carcinoid neuroendocrine tumor? A carcinoid neuroendocrine tumor starts in the cells of the hormone-producing organs in our body. A carcinoid tumor is a type of neuroendocrine tumor that most commonly arises in the gastrointestinal system, which includes intestines, stomach, and esophagus. Carcinoid tumors account for about 1% to 2% of lung cancers. As carcinoid tumors originate from tissue that produces hormones, the main side effect of the condition is the inappropriate release of various hormones in the bloodstream. Carcinoid neuroendocrine tumor can arise in a number of locations categorized into three areas: the foregut, midgut, and hindgut. Lungs and stomach form the foregut area. The midgut comprises of the small intestine, colon, and appendix. The hindgut includes the end of the large bowel, the rectum, and genitourinary tract organs (ovaries and testes). What factors raise a person’s risk of developing a carcinoid tumor? A family history of multiple endocrine neoplasia type 1 : This hereditary condition increases an individual’s risk of developing tumors in the pituitary gland, pancreas, and parathyroid gland. Age : Age seems to be a major factor that plays an integral role, as children rarely develop carcinoid tumors; the average diagnosis age is 55 to 65 years for this condition. Race and gender : Carcinoid tumors are more common among black people than white people, and black men have a higher risk than black women. White men and women have the same risk levels, and after treatment, women tend to live longer. Other medical conditions : Some medical conditions that damage the stomach and reduce acid production increase the risk of developing a carcinoid neuroendocrine tumor. What are the symptoms of a carcinoid tumor? Signs and symptoms of a carcinoid neuroendocrine tumor depend on where the tumor develops: Carcinoid tumors in the lungs : The symptoms of a tumor in the lungs are chest pain, wheezing, diarrhea, shortness of breath, skin flushing (redness and a feeling of warmth on the face and neck), weight gain, particularly around the midsection and back, and pink or purple marks on the skin, which look like stretch marks. Carcinoid tumors in the digestive tract : The symptoms, in this case, are abdominal pain, diarrhea, nausea and vomiting, intestinal blockage, causing an inability to pass stool, rectal bleeding and pain, and skin flushing. What are some effective management tips for the symptoms of carcinoid neuroendocrine tumors? Facial flushing : Avoid stress and ask your doctor about specific foods that cause facial flushing so that you can avoid them. Diarrhea : Ask your doctor for anti-diarrheal medication. Wheezing : Ask for medication that relaxes muscles in the lungs to make breathing easier. Heart problems : Discuss your heart issues with your doctor so that they can prescribe diuretics, which lower the blood pressure. Carcinoid syndrome : Use octreotide on prescription, which is the most effective medication to treat carcinoid syndrome. What is the prognosis for carcinoid neuroendocrine tumor? Carcinoid neuroendocrine tumors can be benign (non-cancerous) or malignant (cancerous). Benign carcinoid tumors are small and can be removed completely. They don’t come back and don’t spread to other parts of the body. They don’t produce any symptoms as well. Malignant carcinoid tumors are large, and their cells can invade and damage the surrounding tissues and organs. Additionally, malignant cells can enter the bloodstream or lymphatic system and can even form new tumors in other parts of the body. Lymph nodes, lungs, bone liver, and skin are the common sites for carcinoid metastases. Carcinoid tumors grow slowly in comparison to other cancers, such as lung, colon, pancreas, or liver cancer. Patients with larger malignant carcinoid tumors (with or without metastasis) can survive and have a good quality of life after proper treatment. Adenocarcinoids, a rare form of carcinoid tumors, are more aggressive than the typical malignant carcinoid tumors.
