Surgery is a common treatment option for breast cancer and may involve either breast-conserving surgery, such as lumpectomy, or mastectomy, which involves the removal of the entire breast. The specific surgical approach is determined based on factors such as the stage of the cancer, tumor size, and patient preferences. This treatment option usually happens pretty quickly, within 3 weeks.

Chemotherapy is a systemic treatment for breast cancer that uses powerful medications to kill cancer cells throughout the body. It may be recommended before surgery to shrink tumors, after surgery to reduce the risk of recurrence, or in advanced cases to slow the progression of the disease. The specific chemotherapy drugs and treatment schedule are tailored to each patient's individual case, considering factors such as cancer stage, tumor characteristics, and overall health.

Hormonal therapy, also known as endocrine therapy, is a systemic treatment option for hormone receptor-positive breast cancer. It works by blocking the effects of hormones that promote cancer growth. It is commonly used after surgery to reduce the risk of recurrence or as a treatment for advanced breast cancer, and the specific medications and duration of therapy are determined based on individual factors and tumor characteristics.

Biological therapy, also known as targeted therapy, is a treatment approach for breast cancer that focuses on specific molecules or pathways involved in cancer growth. It utilizes medications designed to selectively target these specific molecules, such as HER2-targeted therapies for HER2-positive breast cancer.

Biological therapy can be used in combination with other treatments, such as chemotherapy or hormonal therapy, and it aims to block the growth and spread of cancer cells while minimizing damage to healthy cells. The selection of targeted therapy depends on the molecular characteristics of the tumor and may be recommended based on the presence of specific biomarkers or genetic mutations.

Radiation therapy is a localized treatment for breast cancer that uses high-energy radiation to destroy cancer cells and prevent their growth. It is commonly employed after surgery to target any remaining cancer cells and reduce the risk of recurrence. The treatment is carefully planned to deliver precise doses of radiation to the affected area while minimizing damage to surrounding healthy tissues.
