What Cause Cancer Cells To Develop
Multi-factorial: The factors help contribute to all tumor development in general 1. Genetics 2. Mutation inducing factors (examples: smoking, drinking, etc). 3. Aging 3. Unknown causes (there are definitely people without family history or obvious "bad habits" that develop brain tumors). ...Read moreSee 1 more doctor answer
Cancer is a group of diseases that is characterized by uncontrolled cell growth leading to invasion of surrounding tissues that spread to other parts of the body. Cancer can begin anywhere in the body and is usually related to one or more genetic mutations that allow normal cells to become malignant by interfering with internal cellular control mechanisms, such as programmed cell death or by preventing ...Read more
Ultraviolet light: While there is a new study implicating cigarette smoking as a contributing factor, most research points to ultraviolet light (sunshine, tanning bed, welding torch rays) as the most common trigger. More rarely, long term exposure to certain chemicals can also cause this in factory or farm workers whose skin is constantly exposed. A weakened immune system can aid the transformation. ...Read moreSee 1 more doctor answer
Mutate genes: A few of them caused greatly increased cell turnover instead which is the fertile soil in which mutations caused by other agents can be expressed. Remembering that all true cancers are mutagens is a good way to tell which "things that cause cancer" in media / pop reports are probably true (radiation, smoking, mutagenic chemicals) and which ones are bogus / statistical flukes / scare talk. ...Read more
Dna damage: That is either not repaired, or repaired incorrectly. Cell division replicates the mistake, and leads to more errors. ...Read more
Multiple steps: Cancer is multi-step process of accumulating defects in the genome of the cells exposed to various insults, including inherited damage. The changes often start by facilitating the growth of cells and additional damage to the cells accrues that enables them to grow unchecked, acquire the ability to invade and metastasize. A human cancer has about 90 genetic defects. ...Read more

Colon Cancer : There is no direct evidence linking bacterial growth with colon cancer; risk factors traditionally include lack of fiber intake, high fat content in the diet, certain hereditary conditions and family history of the diseases. Some evidence suggests Aspirin can also reduce the risk of colon cancer. Ulcerative colitis and crohn's disease impart an increased risk of cancer. ...Read moreSee 1 more doctor answer
Let's try this..: Simply put, human cells have a "self-destruct" key that kills the cell when it mutates (apoptosis.) when that system fails, the mutated cells begin to grow and replicate outside the normal boundaries of the human system. Those mutated cells rob the healthy system and grow unfettered - a cancer. I hope this helps. Good luck. ...Read more
Do believe the research findings that garlic can cause tumor and cancer cells to undergo apoptosis?
In vitro vs. In vivo: I am unclear about garlic in particular, but let's look at anti-cancer therapy more generally. Many, many (all?) things can kill cancer cells (=apoptosis; there are other modes of cell death, but apoptosis is the most common) in vitro (outside of the body). The predictive ability of in vitro killing to in vivo (in body) effectiveness is not great. ...Read moreSee 1 more doctor answer
Two theories.: Endometriosis is most strongly linked to ovarian cancer. One theory for this association is that there are common risk factors for endometriosis and ovarian cancer to co-occur. The other is that endometrial cells that have spread from the uterus to the ovary can transform into cancer cells via gene mutation. However, it is generally thought that endometriosis is not a direct precursor to cancer. ...Read moreSee 1 more doctor answer
Absolutely: Therapeutic radiation famously causes certain sarcomas. After chernobyl, the worst was thyroid cancers that were thankfully mostly manageable. After hiroshima / nagasaki, there was a lot of leukemia, some increase in breast and other cancers. Home radon ; lung cancer is complicated and politicized. I believe the risk from worthwhile diagnostic x-rays is far lower than some scare-stories. ...Read more
How often do glial cells multiply and divide? Particularly glial cells in the brain stem? What causes cancer to form here? How many mutations?
See below: Cancer is many different disease with different causes. One cause is genetic predisposition. Other causes are use of tobacco and alcohol; exposure to radiation, air pollution; obesity, lack of exercise and hormones. See this site for more info. http://www.cancer.gov/cancertopics/causes. ...Read more
Old age: Red cells have a limited life span of only about 120 days. Some disorders shorten the life span of red cells, e.g., auto-immune hemolytic anemia, hemoglobin disorders like sickle cell disease, malaria, artificial valves, severe exercise etc. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex, if you have sex. ...Read more
Is hypersensetivity syndrome any thing to do with elevated nk cells or does it cause nk cells to be agressive ?
Sun exposure...: The most common eye cancer would be a basal cell carcinoma of the eyelid. This is largely related to excess sun exposure. A rare cancer in the eye is a retinoblastoma which can develop due to a mutation on chromosome 13, called the rb1 gene. This cancer has a good cure rate if detected early. A melanoma is another form of cancer in the eye that frequently harbor gnaq/gna11 mutations. ...Read more
Just read that dvts can be caused by hyper coagulation in the body due to cancer. What blood tests detect cancer? What type of cancer can cause clots?
Probable viral: Pancreas cancer starts out as an intraductal lesion similar to breast DTIC (dacarbazine). It smolders within the ductal system for 15-20 yrs before first signs of ductal wall invasion to become an early pancreatic carcinoma. The TAA that are expressed early are oncofetal in origin and are suppressed at birth to reappear in the tumor as the oncogenic protein. Transformation probably viral induced. ...Read more
