Chemotherapy vs. Radiation: Understanding Cancer Treatments

When it comes to cancer treatment, chemotherapy and radiation therapy are two of the most commonly used methods. Both aim to eliminate cancer cells, but they work in different ways. Understanding these differences can help patients make informed decisions about their treatment.

What is Chemotherapy?

Chemotherapy often called chemo, is a type of cancer treatment that uses medications to destroy cancer cells. These medication travel through bloodstream, reaching cancer cell anywhere in the body. Because chemotherapy affects the whole body, it is known as systemic treatment.

How Does Chemotherapy Works?

Chemotherapy drugs works by targeting and killing cells that divide quickly. Since cancer cells multiply faster than normal cells, chemo helps stop their growth and spread.

Chemotherapy can be given in different ways:

Intravenous (IV): Directly into the vein through a drip.
Oral: In pill or liquid form.
Injection: Directly into the body.

Since it circulates throughout the body, chemotherapy is effective against cancer that has spread to other organs.

When is Chemotherapy Used?

Before surgery (Neoadjuvant therapy): To shrink tumors before removing them.
After surgery (Adjuvant therapy): To kill any remaining cancer cells.
For advanced cancer: To control the disease and improve survival.

Common Side Effects of Chemotherapy:

Because chemotherapy also affects some healthy cells, it can cause side effects such as:

Hair loss
Nausea and Vomiting
Fatigue
Increased risk of Infection ( due to weekend immunity)
Mouth sores
Loss of Appetite

These side effects vary depending on the type and dose of chemotherapy. Some patients experience mild effects, while others may have stronger reactions.

What is Radiation Therapy?

Radiation therapy, also called as radiotherapy, uses high-energy rays to destroy cancer cells. Unlike chemotherapy, which affects the entire body, radiation therapy is a local treatment, meaning it only targets cancer in a specific area.

How Does Radiation Therapy Work?

Radiation damages the DNA of cancer cells, preventing them from growing and dividing. Over time, the body naturally eliminates these damaged cancer cells.

Radiation can be given in two main ways:

External beam radiation: A machine directs high-energy rays to the affected area.
Internal radiation (Brachytherapy): A radioactive implant is placed inside or near the tumor.

Since radiation therapy is focused on one part of the body, it is often used to treat cancers that are localized and have not spread widely.

When is Radiation Therapy Used?

After surgery: To destroy any remaining cancer cells.
Before surgery: To shrink tumors and make surgery easier.
For pain relief: In advanced cancer, radiation can help shrink tumors that cause pain.

Common Side Effects of Radiation Therapy?

Radiation therapy side effects are usually limited to the treated area and may include:

Skin irritation (redness, peeling, or a sunburn-like effect)
Fatigue
Swelling in the treated area
Changes in breast shape or Texture (if used for breast cancer)
These side effects are often temporary and improve after the treatment is completed.

Key Differences between Chemotherapy and Radiation:

One major difference between chemotherapy and radiation therapy is how they work. Chemotherapy is a whole-body treatment that attacks cancer cells wherever they may be, while radiation therapy is a localized treatment focused on a specific area.

Chemotherapy is typically recommended when cancer has spread beyond its original site. It can treat cancer in multiple organ at once. In contrast, radiation is used to directly target a tumor and prevent it from coming back in that area.

Another difference is the way they are given. Chemotherapy involves taking drugs, either through an IV, pills, or injections. Radiation therapy, on the other hand, uses beams of energy from a machine or implants placed near the tumor.

The side effects also vary. Chemotherapy can cause widespread effects like hair loss and nausea, while radiation mainly affects the treated area, causing skin irritation or swelling.

Chemotherapy and Radiation in Breast Cancer Treatment

For breast cancer treatment, chemotherapy and radiation are often used together to ensure the best possible outcome. Dr. Deepak Jha an expert in breast cancer surgery in Delhi, explains that both treatments have important roles in different stages of breast cancer

Chemotherapy is often used before or after breast cancer surgery. When given before surgery, it can shrink the tumor, making it easier to remove. After surgery, it helps destroy any cancer cells left behind to reduce the risk of recurrence.
Radiation therapy is commonly used after a lumpectomy or mastectomy. It ensures that any remaining cancer cells in the breast area are destroyed, lowering the chances of cancer returning.

The choice of treatment depends on factors like the cancer stage, tumor size, and overall health of the patient.

Which Treatment is Right for You?

The decision between chemotherapy and radiation therapy depends on various factors, including:

Cancer stage: If the cancer has spread beyond the breast, chemotherapy is often necessary.
Tumor size and location: If the tumor is confined to one area, radiation may be enough.
Patient’s health: Some patients tolerate one treatment better than the other.
