Although ER - positive tumors represent the
majority of breast cancer cases, they exhibit a wide range of prognoses, histological growth patterns, and treatment outcomes.
But mutations in these two genes account for only 5 to 10 %
of breast cancer cases in the general population, and worldwide, breast cancer remains the most common and most deadly cancer in women.
The American Institute for Cancer Research (AICR) estimates that about one -
third of breast cancer cases could be prevented with weight control, exercise and cutting back on alcohol.
Some mutated genes are inherited: two examples are BRCA1 and BRCA2, which together account for about 5 %
of all breast cancer cases.
These mutations are estimated to account for only 1 - 3 %
of all breast cancer cases and about 15 - 25 % of the familial component of breast cancer.
[2] TNBC accounts for 10 - 15 %
of all breast cancer cases and has a higher rate of mortality than other malignancies.
An inherited predisposition to develop breast cancer accounts for approximately 5 % -10 %
of all breast cancer cases, but is rare in the general population (less than 1 %).
The good news is that IBC is rare, accounting for 1 - 5 %
of all breast cancer cases, according to the National Cancer Institute.
The headline in my paper, Mar. 26, is «Up to a Third
of Breast Cancer Cases Could be Avoided.»
