What Are the Four Treatments for Cancer?

A cancer diagnosis can raise many questions for patients and their families. One of the most common is understanding the treatment options available. Cancer treatment has advanced significantly, and doctors now have different approaches to manage the disease depending on its type, stage and location.

The four major approaches include surgery, chemotherapy, radiation therapy and immunotherapy. Some patients may need only one treatment, while others may benefit from a combination. Understanding these options can help patients make informed decisions with their oncology team.

1. Cancer Surgery

Cancer surgery is a treatment in which a surgeon removes a tumour and, when necessary, some surrounding tissue or nearby lymph nodes. It is commonly considered when cancer is localised and can be safely removed.

The type of surgery depends on the cancer's location, size and stage. Depending on the patient's condition, doctors may recommend open surgery or minimally invasive techniques.

Surgery may be used as the primary treatment or combined with chemotherapy and radiation therapy. A surgical oncologist evaluates the patient's reports and determines whether an operation is appropriate.

2. Chemotherapy

Chemotherapy uses specialised medicines to destroy cancer cells or slow their growth. These medicines may be administered through an intravenous drip or taken as oral tablets, depending on the treatment plan.

Chemotherapy may be recommended before surgery to reduce tumour size, after surgery to target remaining cancer cells, or as the main treatment for certain cancers.

Some patients may experience side effects such as nausea, tiredness, hair loss or changes in appetite. These effects vary depending on the medicines and individual response. Medical oncologists monitor patients throughout treatment and provide supportive care to manage side effects.

3. Radiation Therapy

Radiation therapy uses carefully planned, high-energy radiation to damage cancer cells and prevent them from growing. It is directed towards a specific area of the body while aiming to protect nearby healthy tissues.

It may be recommended to shrink a tumour, treat cancer in a particular area, or reduce the risk of cancer returning after surgery. In some cases, radiation therapy is combined with chemotherapy.

Modern technologies such as LINAC-based radiation therapy help specialists plan and deliver treatment with precision. The number of sessions depends on the cancer type, treatment objective and patient's medical condition.

4. Immunotherapy

Immunotherapy is a type of cancer treatment that helps the body's immune system recognise and fight cancer cells. Unlike conventional chemotherapy, which directly targets rapidly dividing cells, immunotherapy works by supporting the immune system's response against cancer.

It may be suitable for certain cancers depending on specific tumour markers and other medical factors.

One specialised form is CAR T-cell therapy. In this treatment, a patient's T-cells are collected and modified to recognise particular cancer cells. CAR T-cell therapy is used for selected blood cancers, including certain cases that have not responded to previous treatments. It is not suitable for every cancer patient.

How Is the Right Cancer Treatment Selected?

There is no single treatment that works for every type of cancer. An oncologist considers several factors before recommending a treatment plan, including:

• Type and stage of cancer

• Tumour size and location

• Biopsy and diagnostic test results

• Specific cancer markers

• Patient's age and overall health

A multidisciplinary tumour board, involving specialists from different medical fields, can help evaluate the available options and plan suitable care.
