Understanding Chemotherapy in Breast Cancer Treatment

Chemotherapy uses a combination of targeted medications to destroy cancer cells and inhibit their growth. The specific drug protocols vary based on the disease stage and tumor location. This guide offers key details about breast cancer types, stages, and how chemotherapy fits into treatment plans.

What is breast cancer?

Breast cancer occurs when abnormal cells rapidly multiply within breast tissue.

Typically manifests as a lump, changes in breast shape, or nipple discharge.

Risk factors include obesity, inactive lifestyle, dense breast tissue, and genetic predispositions.

Incidence increases with age.

The intensity of chemotherapy is tailored based on cancer stage and spread.

Breast cancer staging explained

Stage 0 - Very early, localized cancer that responds well to treatment. Surgery removes affected tissue, often combined with radiation to minimize recurrence.

Stage 1 - Tumors up to 2 cm, possibly spreading to nearby lymph nodes. Treatment involves surgery and hormone therapy; chemotherapy may not be needed if hormone therapy is sufficient.

Stage 2 - Tumors between 2 and 5 cm, with potential lymph node involvement. Treatments include surgery, radiation, and systemic chemotherapy to target the disease throughout the body.

Stage 3 - Larger tumors (over 5 cm) with extensive lymph node spread, possibly invading surrounding tissues. Approach includes combined surgery, radiation, and chemotherapy.

Stage 4 - Cancer has spread to distant organs like brain, lungs, bones, or liver; considered incurable. Focus is on symptom management and slowing progression.

Common symptoms of breast cancer

Breast lumps or thickening

Elevated body temperature over 100.4°F

Nipple discharge or changes in skin texture

Persistent cough or chest discomfort

Throat swelling or discomfort

Urinary issues such as pain or blood in urine

Gastrointestinal signs like nausea, vomiting, or blood in stool

Typical chemotherapy drugs for breast cancer

Platinum compounds (cisplatin, carboplatin)

Anthracyclines (doxorubicin, epirubicin)

Taxanes

Vinorelbine

Gemcitabine

Capecitabine

Eribulin

Ixabepilone

How is chemotherapy administered?

Oral chemotherapy allows patients to take medicines at home with regular check-ins.

Intravenous treatments require hospital visits, especially during initial cycles, which might involve inpatient stays.

While effective, chemotherapy can harm healthy cells, causing side effects like fatigue, nausea, hair loss, and weakened immunity. These effects are temporary and improve after treatment ends.
