Breast cancers are believed to involve several factors including:
(1) Personal factors:
1. Women with no children or late first pregnancies (aged 30
years+).
2. Someone who takes the hormone estrogen for a long time.
3. Someone who has suffered from breast lesions that are
diagnosed as lobular or ductal “Atypical Hyperplasia,”.
4. Women who have n early onset of menstruation.
5. Women who enter menopause later and have had more
exposure to the hormones estrogen and progesterone.
(2) Dietary factors:
The relationship between alcohol and breast cancer is consistent
among associations of dietary factors and breast cancer risks,
and is likely related to alcohol`s (beer, wine, and liquor) ability to
increase estrogen levels. Most doctors recommend no more than
seven alcoholic beverages per week for women.
(3) Weight & Physical Inactivity factors:
10 kg weight gain after menopause is associated with an
increased risk of post-menopausal breast cancer. Indirect
evidence exists indicating that there is an inverse relationship
between amount of physical activity levels and one`s risk of
breast cancer.
(4) Family History of Breast Cancer:
A family history of breast cancer or other cancers found in
association with Breast Cancer (colon, brain, ovarian, etc.) can
increase a woman`s risk for breast cancer. It is important to know
which family members were diagnosed with that type of cancer at
what age.
(5) Radiation or other external environment factors:
Exposure to significant doses of radiation, etc.
