Blacks are more likely to have aggressive colorectal cancer according to U.S. research studies.
Now researchers have found a gene mutation which they believe may be at the basis of this.
The presence of this gene, Pro72 allele of p53, was associated with more than twice as many deaths from colorectal cancer.
Other known risk factors for colorectal cancer include:
- a family or personal history of colorectal cancer [Colorectal cancer therapy]
- ulcerative colitis
- being over the age of 50
- having polyps
- diets high in fat and low in fiber
- being female and having had ovarian, uterine, or breast cancer
Colorectal cancer can be present without causing any symptoms in its early stages [Colorectal cancer symptoms]. This is why it is so important to have regular screenings.
If you have a change in how often you have a bowel movement, or a feeling that your bowel is not completely emptying, talk to your doctor. Stools that are bright red or tarry black should also be reported to your physician.
Research shows that women with a history of cancer of the ovary, uterus, or breast have a somewhat increased chance of developing colorectal cancer. Also, a person who has already had colorectal cancer may develop this disease a second time.
