What Are The Side Effects Of Chemotherapy For Breast Cancer?
Introduction
One of the options for treatment of breast cancer is chemotherapy, with a very high percentage of patients recommended chemotherapy. This is especially higher in younger women when compared with women aged more than 65 years. Here is a quick look at the side effects of chemotherapy for breast cancer to help patients understand the possible outcomes and the options available.
What Are The Common Symptoms Of Breast Cancer?
Before looking at the side effects of chemotherapy for breast cancer here is a look at the commonly reported symptoms of breast cancer. This varies based on the type and stage of the disease. Early breast cancer often shows few or no symptoms, which makes regular screening essential for early detection.
Common symptoms of breast cancer:
- Changes in the breast
- Formation of a lump or thickening in the breast or underarm.
- Changes in the size or shape of the breast.
- Swelling in part of the breast, even without a noticeable lump.
Changes in the skin:
- Redness or flaky skin around the nipple area.
- Dimpling of the skin, resembling the texture of an orange peel.
- Warmth or inflammation of the breast skin.
Changes in the Nipple:
- Nipple turning inward (inversion).
- Unusual nipple discharge.
- Persistent pain in the nipple or breast.
It is important to note that not all lumps or changes in the breast indicate cancer. Many changes can be benign. However, regular screening, including mammograms, is crucial for detecting breast cancer early and improving treatment outcomes.
Genetic Testing for Breast Cancer – Testing for BRCA1 and BRCA2 gene mutations can identify inherited genetic risks for breast cancer. Advanced genetic testing facilities in Tamil Nadu provide solutions for detailed analysis. A simple blood or saliva sample is analyzed to detect potential genetic mutations, helping individuals understand their risk and take preventive measures.
What Is Chemotherapy?
As part of understanding of the side effects of chemotherapy for breast cancer, here is a quick look at chemotherapy. Chemotherapy is a major cancer treatment that uses powerful drugs to kill cancer cells and prevent their growth. It helps stop cancerous cells from spreading and can be used alone or alongside other treatments, such as surgery or radiation. Below is an overview of chemotherapy for breast cancer:
How chemotherapy works – Chemotherapy targets rapidly dividing cells, which include cancer cells. However, a small percentage of healthy cells may also be affected during treatment, leading to side effects.
Goals of chemotherapy:
- To completely eliminate cancer.
- To destroy remaining cancer cells after surgery or radiation.
- To shrink tumors before surgery.
- To relieve symptoms in advanced cancer.
Drugs commonly used in chemotherapy:
- Cisplatin
- Paclitaxel
- Doxorubicin
- 5-Fluorouracil
These drugs can be administered in various ways, including:
- Intravenously (through a vein).
- Orally (as pills or capsules).
- Through injections into the muscle.
- Topically (as creams applied to the skin).
What Are The Different Stages Of Breast Cancer?
Before looking at the side effects of chemotherapy for breast cancer, let us understand the different stages of breast cancer. This is categorized into stages based on the size of the tumor, and its spread to nearby lymph nodes. Main stages of breast cancer include:
Stage 0: Non-invasive – When cancer cells are confined to the ducts of the breast only. This is considered as the earliest form of breast cancer and can be highly treatable.
- Stage I: Early-stage invasive
- Stage IA: When the tumor is 2 cm or smaller.
- Stage IB: When there are small groups of cancer cells smaller than 2 mm in nearby lymph nodes without any tumor in the breast, or if the tumor is 2 cm or smaller.
- Stage II: When the tumor is larger or when there is limited lymph node involvement
- Stage IIA: When there is no tumor in the breast, but present in a few lymph nodes.
- Stage IIB: When the tumor is of a particular size and present in a few lymph nodes.
- Stage III: Locally advanced tumor
- Stage IIIA: When cancer has spread to more lymph nodes, or the tumor is larger in size.
- Stage IIIB: When the tumor has expanded into the chest wall or skin.
- Stage IIIC: When cancer has spread to more lymph nodes.
- Stage IV: Metastatic breast cancer – When cancer has spread to other parts of the body, like bones, liver, lungs, or brain. This stage is the most advanced and is regarded as incurable, and is typically managed with treatment.
- Recurrent breast cancer: When cancer returns post treatment. This could be either in the breast, or nearby lymph nodes, or other organs.
What Are The Different Options In Cancer Treatment?
The choice of treatment depends on the stage of cancer, its characteristics, and the overall health of the patient. Common treatment options include:
- Surgery – To remove the cancerous tissue.
- Radiation therapy – Through high-energy beams to destroy targeted cancer cells. Types include:
- External beam radiation: By a machine outside the body.
- Internal radiation: By radiation inside the body near the tumor site.
- Chemotherapy: By drugs to kill cancer cells or prevent growth. Administered either before or after surgery.
- Hormone therapy: Blocks hormones that cause breast cancer growth. Usually after surgery and a preventive option for high-risk patients.
- Targeted therapy: Focuses on specific proteins or genetic mutations that are responsible for cancer growth.
- Immunotherapy: This boosts the ability of the immune system ability to identify and attack cancer cells. Usually combined with chemotherapy for better effectiveness.
Quick Overview Of Breast Reconstruction
This is a surgical procedure that restores the appearance and size of the breast. However, the procedure does not bring back the natural sensation to the breast. Types of breast reconstruction include:
- Implants: Through saline or silicone implants to recreate the breast.
- Autologous reconstruction: Through the patient’s own tissue, from the abdomen, back, thighs, or buttocks, to reconstruct the breast.
- Combination reconstruction: Through implants and autologous tissue for a more natural appearance.
- Oncoplastic surgery: Through cancer surgery combined with reconstructive methods for best results.
