Breast cancer chemotherapy side-effects

Breast cancer is a type of cancer where the cells in the breast grow unnaturally in one or both breasts and can spread all over the area. It depends on which cell of the breast that has turned into cancer. A breast is made up of 3 different parts i.e lobules, duct, and connective tissue. To treat breast cancer one of the frequently used treatment methods is chemotherapy. Chemotherapy is again administered as oral, IV, IM, or subcutaneous.

Chemotherapy is a traditional and most common approach to treat cancer via curative or palliative intent.

Chemotherapy in breast cancer uses drugs to target and destroy the cancerous cells found in the breast. The drugs of chemotherapy are directly injected into veins through a needle or could also be taken orally.

Chemotherapy could be given with other treatments such as hormonal, radiation, or surgical therapy.  Chemotherapy itself increases the change in condition and increases cure while decreasing the risk of recurrence, fighting the symptoms, or helping people with living a better quality of life.

In case of rapid spread or recurrence, it can also help in the control of breast cancer which helps to live longer or can also help ease with symptoms.

Chemotherapy in breast cancer carries side effects that ranges from mild and moderate to severe. Consultation with the oncophysician helps in the process and to take better treatment decisions during the process.

Chemotherapy for breast cancer may be given in the conditions like:

Chemotherapy after surgical procedure for breast cancer

After the surgical procedure to destroy and remove the cancerous cells from the breast, the oncophysician may recommend chemotherapy to kill the undetected cancer cells and reduces the risk of recurrence. This can also be termed as Adjuvant chemotherapy.

Adjuvant therapy is also recommended when there is a high risk of recurrence or metastasis (spread in other parts), even after there is no evidence of cancer after surgery. The risk is higher if the cancerous cells are there near lymph nodes near the breast.

Chemotherapy before surgical procedure for breast cancer

When chemotherapy is given before a surgical procedure it’s termed as neoadjuvant therapy to shrink the larger cancer. This can also allow

  • Surgeon to remove cancer completely.
  • Allows the surgeon to remove only the cancerous part rather than the complete breast.
    • Make less invasive lymph node surgery as decreases the disease extent in lymph nodes.
  • Decreases the recurrence of cancer.
  • For the proper understanding of oncophysician that can help them to come over proper prognosis and treatment plan.

Neoadjuvant therapy is usually used for:

  • Inflammatory breast cancer
  • HER2-positive breast cancer
  • Triple-negative breast cancer
  • High-grade breast cancers
  • Cancers that have spread in lymph nodes
  • Large breast cancers

Chemotherapy acting as the primary treatment for advance stage breast cancer

When breast cancer spreads to other parts of the body and surgery is not possible, chemotherapy is a primary treatment that could be used with targeted therapy.

Certainly, the main aim of chemotherapy is palliative care to improve the quality of life rather than just curing the disease.
