Physical Activity and Breast Cancer Prevention
By: Ashlie S. and Morgan I.
What is “breast cancer?”
• Malignant tumor in each side of breast
• Stage 0- No evidence of cancer cell. No cancerous abnormal cells.
• Stage I- Cancer cells breaking through normal surrounding breast tissue. Two types. IA- Tumor measures 2cm and hasn’t spread outside breast. IB- No tumor, but large group of cells found in lymph nodes.
• Stage II- Two subcategories. IIA- No tumor, cancer found in lymph nodes near breast. IIB- Tumor found, larger than 2mm but smaller than 5mm, not in axillary lymph nodes.
• Stage III- No tumor or tumor found, up to 5mm in lymph nodes near breast, or in breast.
• Stage IV- Tumor found, cancer cells have spread beyond breast and lymph nodes into organs like, lungs, skin, bones, liver and or brain.
• Four characteristics-
1) Based on size of tumor and or cancer cells
2) Invasive or non-invasive
3) If it is in lymph nodes or not
4) If cancer spreads to other parts of the body
Statistics of breast cancer
• Females- 192,000 women diagnosed from 2009-2013
1 in 8 women are diagnosed with breast cancer
• Males- 2,140 men diagnosed from 2011-2013
1 in 1,000 men are diagnosed with breast cancer
• Survivors- From 2011-2013 2.6 million survivors
• Non-survivors- 39,520 women died from breast cancer, and 400 males have died from 2011-2013
• Recurrence- 25% of survivors will have second recurrence
• Non-recurrence- 75% have not had recurrence, but this doesn’t mean they cant have recurrence
Risk Factors
• Age- Chance increases as women age. 2/3 women are older than 55 when diagnosed.
• Gender- Women more likely, but men aren’t immune to it
• Weight- More likely to experience a recurrence or die
• Race- White women are more likely. African Americans are more likely to die once diagnosed. Hispanics and Native Americans at lower risk
• Family history- More likely to get if blood relatives have had cancer. Mother, sister, daughter that have relative with cancer double their chances.
Physical Activity with breast cancer
• Physical activity- Any bodily movement by skeletal muscles
• Breast cancer occurs more in women who are inactive than their active counterparts
• Prevents tumors by lowering hormones
• 32% women who were diagnoses are physically active
• Doctors suggest up to 30 minutes per day
Why it helps
• Studies show that exercise is safe during and after cancer and it’s treatment. Helps improve the patient in many ways
