Risk factors for breast cancer
Advanced age, History of breast cancer, first degree relative with breast cancer, BRCA-1 or BRCA-2, Menarche at an early age, Hormone therapy (or high levels of estrogen), HRT, No children or having children late, Obesity, Smoking, Atypical hyperplasia
Dimpling
Nipple retraction which makes the nipple look flat, may only be apparent with lifted arms, laying down or with compression
Edema (Peau d’Orange)
Lymphatic obstruction produces edema. Gives a “pigskin” or orange peel look. Suggests cancer
Fixation
Asymmetry, distortion, or decreased mobility with the elevated arm maneuver. As cancer becomes invasive, the fibrosis fixes the breast to the underlying muscle
Deviation of nipple pointing
Cancer causing fibrosis in the mammary ducts which then pulls nipple angle towards it
Gynecomastia
Benign enlargement of male breast that occurs when estrogen concentration exceeds testosterone levels. In older men it is bilateral whereas in adolescents it is usually unilateral
Male breast cancer signs
Similar to those of a woman
Benign “Fibrocystic” Breast Disease
Bilateral usually, Tender masses that occur with numerous symptoms like swelling, tenderness, mastalgia (severe pain), Nodularity (significant lumpiness), Dominant lumps, Nipple discharge, Infections and inflammations
Breast Cancer signs
Solitary, unilateral, non-tender mass. Borders are irregular, Often painless, Unilateral, Found in women between the ages of 30-80
Fibroadenoma
Benign tumors, most commonly present as self-detected in late adolescents.
Solitary non-tender mass that is solid, firm, rubbery, and elastic. Usually no axillary lymphadenopathy
Fibroadenoma: common age it occurs
15 - 30 yrs, occurs up to 55
Benign Breast Disease: common age it occurs
30 - 55, decreases after menopause
Cancer: common age it occurs
30 - 80 yrs, risk increases after 50
