Cancer (Definition)

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

Colon cancer chemo necessary?

Depends on stage: Chemotherapy is never used for stage 1 cancers (early). It is sometimes used in stage 2 cancers (early but more advanced than stage 1). Chemotherapy is definitely beneficial in stage 3 cancers (locally advanced) and in stage 4 cancers (distant spread). ...Read more

Is colon cancer fast-growing?

Is colon cancer fast-growing?

Can be: The fastest-growers are the ones that follow genetic pathways associated with the lynch loci. They may not even be preceded by a polyp -- colonoscopy can be clean one year, and a year later, there's a cancer. That's actually quite fast as cancers go. Hope this helps. ...Read more

Are breast cancer and colon cancer linked?

Are breast cancer and colon cancer linked?

Not directly usually: There is debate about how closely these 2 cancers are related. Both have hereditary natures and are more common generally in obese patients. Both often begin with more benign precursor lesions like dcis for breast cancer and benign polyps for colon cancer. Both are very common but there is little evidence that having either predisposes to having the other. ...Read more

Why is the colon prone to cancer in hnpcc (hereditary nonpolyposis colorectal cancer)?

Why is the colon prone to cancer in hnpcc (hereditary nonpolyposis colorectal cancer)?

Genetic mutations: HNPCC or hereditary nonpolyposis colorectal cancer is an autosomal dominant genetic condition that has a high risk of colon cancer The disease first described by Lynch and is associated with other cancers including endometrial ovary and stomach. The increased risk is due to inherited mutations that impair DNA mismatch repair. .Individuals with HNPCC have an 80% lifetime risk for colon ca. ...Read more
