Chemotherapy: How It Works, Side Effects, and Treatment Options

Chemotherapy is a type of cancer treatment that uses specialised drugs to destroy cancer cells, prevent their spread, and shrink tumours. While it is primarily associated with cancer, chemotherapy can also be used to treat certain non-cancerous conditions like autoimmune diseases. Often administered as part of a comprehensive care plan, chemotherapy is tailored to each patient based on their diagnosis, overall health, and treatment goals.

How Chemotherapy Works

Chemotherapy works by targeting cells that divide rapidly, a characteristic of cancer cells. The drugs are designed to interfere with cell division, which slows the growth of cancerous tumours or eradicates them entirely.

• Delivery methods: Chemotherapy drugs can be administered through various methods, such as intravenous injections, oral tablets, or localised treatments directly at the tumour site.
• Treatment cycles: It is usually given in cycles to allow the body time to recover between sessions. The duration and frequency of treatment depend on the type and stage of cancer.
• Combination therapy: In many cases, chemotherapy is combined with other treatments, such as radiation therapy or surgery, for more effective results.

Types of Chemotherapy

There are several types of chemotherapy drugs, each with a unique mechanism of action.

1. Alkylating agents

These drugs damage DNA and prevent cancer cells from reproducing.

2. Antimetabolites

They interfere with DNA and RNA growth by substituting normal building blocks of cells.

3. Plant alkaloids

Derived from natural products, these drugs block cell division during specific stages of the cell cycle.

4. Antitumor antibiotics

These inhibit the enzymes that cancer cells need to replicate their DNA.

5. Targeted therapy

Unlike traditional chemotherapy, targeted drugs are designed to attack specific cancer cell proteins or genes.

Benefits of Chemotherapy

The chemotherapy treatment offers numerous benefits, making it an essential part of cancer care:

• Shrinks tumours: Helps reduce the size of tumours, making surgery or radiation more effective.
• Prevents spread: Controls the spread of cancer to other parts of the body.
• Reduces symptoms: Alleviates symptoms caused by tumours pressing on organs or tissues.
• Enhances survival rates: Increases the chances of long-term survival for many types of cancer.
• Combines effectively: Complements other treatment modalities like surgery and radiation therapy.

Side Effects of Chemotherapy

While chemotherapy is a powerful tool in the fight against cancer, it is also known for its side effects due to its impact on healthy, rapidly dividing cells. Common chemotherapy side effects include:

• Hair loss: A temporary but common side effect due to damage to hair follicle cells.
• Nausea and vomiting: Many patients experience digestive discomfort after treatment.
• Fatigue: A significant reduction in energy levels is common.
• Increased infection risk: Chemotherapy can lower white blood cell counts, compromising immunity.
• Mouth sores: The sensitive lining of the mouth and throat can be affected.
• Appetite changes: Taste alterations and decreased appetite are frequent concerns.

Treatment Options

Chemotherapy can be personalised based on the type and stage of cancer. Common chemotherapy treatment options include:

1. Curative chemotherapy

Aims to eliminate cancer entirely.

2. Adjuvant chemotherapy

Given after surgery to destroy any remaining cancer cells.

3. Neoadjuvant chemotherapy

Administered before surgery or radiation to shrink tumours.

4. Palliative chemotherapy

Focuses on relieving symptoms and improving quality of life.

5. Combination therapy

Uses a mix of chemotherapy drugs or combines chemotherapy with other treatments like immunotherapy.
