Breast cancer forms when something goes wrong with the cells in the breast. Normally, cells grow and divide in an organized way, but in breast cancer, some cells start growing uncontrollably and form a lump called a tumor. These abnormal cells can sometimes spread to other parts of the body if not treated. Things like genetics, hormones, and lifestyle can play a role in causing these cells to become cancerous. That's why it's important to catch breast cancer early through check-ups and screenings, so it can be treated before it spreads.

- Healthy Diet: Eat fruits, veggies, whole grains, and lean proteins; limit processed foods and red meat.
- Stay Active: Engage in regular physical activity like walking, swimming, or dancing.
- Limit Alcohol: If you drink, do so in moderation; excess alcohol increases risk.
- Maintain Weight: Aim for a healthy weight through balanced eating and activity.
- Breastfeeding: If possible, breastfeed your baby—it's protective.
- Hormone Therapy: Discuss risks and benefits of hormone replacement therapy with your doctor.
- Screenings: Follow recommended mammogram guidelines for early detection.
- Family History: Be aware of family breast cancer history and inform your doctor.
- Self-Exams: Check your breasts regularly and report any changes.
- Environmental Care: Minimize exposure to toxins and radiation.

The tumor and a small amount of surrounding tissue are removed while preserving most of the breast. It's often followed by radiation therapy.

The entire breast is removed. Types include:

- Simple Mastectomy: Removes breast tissue and possibly nipple.
- Modified Radical Mastectomy: Removes breast tissue, some lymph nodes, and possibly chest muscles.
- Double Mastectomy: Removes both breasts, often for preventive or personal reasons.
