In this video I will tell the 15 proven causes / risk factors for breast cancer.
The science world is yet to particularise anything as the cause of breast cancer. Thus, for now, we shall talking about the risk factors for breast cancer and not causes.
1. SEX: Breast cancer is commoner n women than in men. The reason is because the breasts of men are rudimentary while that of women are well developed. Secondly, the hormone that drives breast cancer is estrogen, and it is a feminine hormone.
2. AGE: MOST breast cancers are diagnosed after the age of 50 years according to CDC.
3. GENETIC MUTATION: The particular genetic mutation that has been implicated is the BRCA MUTATION.
4. EARLY MENARCHE – Menarche is the first menses you experience as a woman. If it comes early , you have a wide range of time to be exposed to estrogens.
5. LATE MENOPAUSE – MENOPAUSE is the last menses, if it comes late, your risk of breast cancer is increased because of large amount of time you are exposed to estrogen.
6. Increased breast Density – The more dense the breast, the more the chances of breast cancer. The density of the breast is a function of connective tissues, the more connective tissues the more dense, the more fat, the less dense.
7. FAMILY HISTORY OF BREAST CANCER: If you have a first degree relative (mother, sister, daughter, brother) with breast cancer, it increases your chances of coming down with breast cancer.
8. FAMILY HISTORY OF OVARIAN CANCER: Based on same principle in No. 7 above.
9. Radiation therapy: Those that were irradiated especially in the chest region during their childhood age has been implicated to stand a risk of breast Cancer.
10. DRUGS: Drugs that have been implicated are diethylstibestrol, some oral contraceptives, hormone replacement therapy.
11. FIRST PREGNANCY AFTER THE AGE OF 30YEARS: This is because pregnancy is protective. The more pregnant you become., the less your chances of breast cancer.
12. NOT BREASTFEEDING: This deprives you of lactational amenorrhea, thereby exposing you to oestrogen and increasing your chances of breast cancer. Lactational amenorrhea means no menses because you are breastfeeding. Breastfeeding is protective of breast cancer.
13. ALCOHOL: It increases the risk of breast Cancer by increasing the oestrogens level and estrogen receptors.
14. SMOKING: Over 60 carcinogens have been identified in tobacco smoke. These cause several types of cancer – bladder cancer, lungs cancer, liver cancer as well as breast cancer.
15. NIGHT SHIFT WORKERS: Like nurses and flight attendants. Their hormonal balance is altered.
