Transcript of Breast Cancer Awareness

About 1 in 8 will develop Breast cancer over the course of her lifetime.

About 5-10% of Breast Cancers can be linked to gene mutations inherited from one’s mother or father.

About 70-80% of breast cancers occur in women who have no family history of breast cancer.

The most significant risk factors for breast cancer are gender (being a woman) and age (growing older).

More than 1 in 4 cancers in women (about 28%) are Breast Cancer.

Every 13 minutes a woman dies of breast cancer.

Breast cancer is the leading cause of cancer death in women between ages of 15 and 54, and the second cause of cancer death in women 55 to 74. Breast Cancer Awareness There are many different types of Breast Cancer Invasive Ductal
Carcinoma Most common

Begins in duct's walls where it reaches the fatty tissue of breast.

Can metastasize

Accounts for 70% of all Breast Cancers. Invasive Lobular
Carcinoma Second most common

Begins in the terminal ducts of the breast milk-producing glands.

Accounts for 10% of all Breast Cancer. Medullary
Carcinoma Accounts for 3-6% of all Breast Cancer.

Prognosis for medullary carcinoma is better than for women with other types of invasive ductal or lobular carcinoma.

BRCA1 mutation is associated with this type of cancer. Breast Cancer can be detected if mammograms are done more frequently. Breast health begins with you. Breast Cancer can be detected with a simple mammogram or a self examination. Signs & Symptoms A change in how breast or nipple feels




A change in how breast or nipple looks





Nipple discharge
Tenderness
A lump
Thickening in or near breast or underarm


Change in the size or shape of breast or nipple

Skin of the breast, areola or nipple may appear:








Slightly inward.


Scaly, red or swollen
Ridges or pitting that resembles skin of an orange Done By: Lisabeth Zuniga Senior Project Statistics The numbers don't lie. What is Breast Cancer? Breast cancer is an uncontrolled growth of breast cells.

Cancer occurs as a result of mutations, or abnormal changes in the genes responsible for regulating the growth of cells and keeping them healthy. Healthy new cells take over as old ones that die out. But over time, mutations can “turn on” certain genes and “turn off” others in a cell. That changed cell gains the ability to keep dividing without control or order, producing more cells just like it, forming a tumor. Knowing it exists is not enough.
Get informed. Pass it on. Risk Factors Risk factors you CANNOT change Risk factors you CAN change Age and gender Genes Family history of Breast Cancer Menstrual Cycle Radiation Diethylstillbestrol Childbirth Alcohol use Hormone Replacement Therapy Obesity Treatments Surgery Radiotherapy Chemotherapy Hormone Therapy Biological Therapy Removes the malignant tumour from the breast. If detected early only the tumor can be removed. In other cases patient undergoes a mastectomy where breast is removed. Hormones can affect the growth of some breast cancer cells. They’re used to lower the levels of oestrogen and progesterone. Cells that are dividing are damaged by radiation and as the cancer cells are more likely to be dividing they are more likely to be killed during radiation than normal cells. Drugs are used to kill cancer cells. These drugs circulate through the body in the blood system where they can get to cancer cells wherever they are. Biological therapy uses laboratory made antibodies designed to target certain cells. Herceptin, a laboratory developed antibody, targets cancer cells.
