  2. BRCA mutation - Wikipedia

    en.wikipedia.org/wiki/BRCA_mutation

    Men with a BRCA mutation have a dramatically elevated relative risk of developing breast cancer, but because the overall incidence of breast cancer in men is so low, the absolute risk is equal to or lower than the risk for women without a BRCA mutation. [9]: Ch8 Approximately 1% to 2% of men with a BRCA1 mutation will develop breast cancer by ...

  3. BRCA2 - Wikipedia

    en.wikipedia.org/wiki/BRCA2

    Analysis of mutations that occur with high frequency also permits the study of their clinical expression. [46] A striking example of a founder mutation is found in Iceland, where a single BRCA2 (999del5) mutation accounts for virtually all breast/ovarian cancer families. [47] [48] This frame-shift mutation leads to a highly truncated protein ...

    The National Comprehensive Cancer Network recommends self-breast examination starting at age 35 for men with mutations in either BRCA gene. [5] Mutations in other genes such as CHEK2, PALB2, PTEN, [33] ATM [4] and RAD51L3 (also termed RAD51D) [21] have been reported to occur uncommonly in, and may confer an increased risk of developing, MBC ...

    [3] [4] It is also the most common form of breast cancer occurring in men, accounting for 85% of cases. [5] [6] The incidence of ductal carcinomas as a whole is 86.3 cases per 100,000 women, with the incidence increasing sharply for women over 40 years of age and peaking at 285.6 cases per 100,000 for women between 70 and 79.

  7. Risk factors for breast cancer - Wikipedia

    en.wikipedia.org/wiki/Risk_factors_for_breast_cancer

    The risk over a woman's lifetime is, according to one 2021 review, approximately "1.5% risk at age 40, 3% at age 50, and more than 4% at age 70." [5] In the United States, about one in eight women (~13%) and one in 800 men (~0.13%) will be diagnosed with breast cancer at some point during their lives.

  8. Anticancer gene - Wikipedia

    en.wikipedia.org/wiki/Anticancer_gene

    BRCA gene mutations: The tumor suppressing BRCA genes frequently help in cancer prevention. They control how cells divide and develop and help repair DNA damage BRCA gene abnormalities, however, can the likelihood of having specific cancers is raised. Cancers BRCA1 and BRCA2 are the two BRCA recognized cancer-causing gene alterations.

  9. PALB2 - Wikipedia

    en.wikipedia.org/wiki/PALB2

    Prophylactic mastectomy should be considered for women that had breast cancer and a PALB2 mutation. [21] [22] Biallelic mutations in PALB2 (also known as FANCN), similar to biallelic BRCA2 mutations, cause Fanconi anemia. [7] Mutations in this gene have been associated with an increased risk of ovarian, breast and pancreatic cancer. [23]
