Where/what organ system in the body?

Reproductive system- Mainly the breast tissues- Lactose lobes/ducts

Cancerous Normal

Rate of breast cancer worldwide

Highest rate – United States “Hamburger Country”(International Agency for Research on Cancer)

Rate of breast cancer worldwide

Lowest Rate – China “Noodle Country” & Africa “Marathon Country”

Affected ages(Dr. Roger Henderson, GP)

Between: 50 yrs old and 70yrs old

Symptoms(American Cancer Society)

LumpsSwellingSkin changes

Risk Factors

– Changes in DNA– Alcohol consumption – Not having children or having them later in life– Not breast-feeding– Overweight or obese– Lack of exercise– Night Work (not proven yet)

(American Cancer Society)

Diagnosis (Screening and Testing)

– Blood test – MRI – X-ray– CT scan– PET scan– Ultrasound– Breast Biopsy– Mammogram

PET scan CT scan

Types of breast cancer

– Ductal carcinoma in situ (DCIS)– Invasive ductal carcinoma (IDC)– Invasive lobular carcinoma (ILC)– Inflammatory breast cancer– Male breast cancer– Recurrent breast cancer– Metastatic breast cancer

(American Cancer Society)

Stages of Cancer• Stage 0 - non-invasive; no evidence of cancer

cells• Stage I - started to invade the tissues in the

breast• Stage II - invasive breast cancer found in the

axillary (arm pit) lymph nodes• Stage III - inflammatory breast cancer• Stage IV – metastatic cancer; cancer cells that

have spread throughout the body organs

Treatments

Surgery: Lumpectomy (tomy = “to cut”)MastectomyAxillary lymph node dissection

Chemotherapy

Radiation therapy

Lifespan (Prognosis)In 5-year survival, ___ out of 100 cancer patients will survive.

• Stage 0 = 99 • Stage 1 = 92• Stage 2 = 65• Stage 3 = 44• Stage 4 = 14
