What Is Immunotherapy?

Immunotherapy is an advanced cancer treatment that helps the body’s immune system recognize and fight cancer cells. Normally, the immune system protects the body against infections and abnormal cells.

However, cancer cells can sometimes evade immune detection and continue growing. Immunotherapy helps strengthen or modify the immune response to target these cancer cells more effectively.

Unlike conventional chemotherapy, which directly destroys rapidly dividing cells, immunotherapy works by supporting the immune system’s ability to fight cancer.

Depending on the type and stage of cancer, doctors may recommend immunotherapy alone or in combination with chemotherapy, radiation therapy, or targeted therapy.

Different types of immunotherapy include immune checkpoint inhibitors, monoclonal antibodies, cancer vaccines, and certain cell-based therapies. These treatments may be beneficial for cancers such as lung cancer, melanoma, kidney cancer, bladder cancer, and some types of blood cancer.

However, their effectiveness varies depending on the cancer type, individual health, and specific tumor characteristics.

Before starting treatment, an oncologist evaluates the patient’s medical history, cancer stage, diagnostic reports, and, when appropriate, biomarker or molecular testing results to determine whether immunotherapy is suitable.

Immunotherapy Side Effects

Although immunotherapy can be an effective cancer treatment, it may cause side effects. These occur because activating the immune system can sometimes cause it to attack healthy tissues along with cancer cells.

The severity of side effects varies from patient to patient. Some individuals experience mild symptoms, while others may develop complications requiring immediate medical attention.

Common side effects of immunotherapy include:

• Fatigue: Patients may experience persistent tiredness, weakness, or reduced energy levels.
• Skin reactions: Rashes, itching, and skin irritation may occur during treatment.
• Digestive problems: Diarrhea, nausea, abdominal discomfort, and reduced appetite are possible.
• Flu-like symptoms: Fever, chills, muscle aches, and headaches may develop.
• Hormonal changes: Immunotherapy can affect hormone-producing glands, potentially causing thyroid problems or other endocrine disorders.
• Serious side effects: In some cases, immunotherapy may cause inflammation of the lungs, liver, intestines, kidneys, or heart. These complications can become serious if not recognized and treated promptly.

Patients should inform their oncologist about new or worsening symptoms, even if they appear mild. Severe breathlessness, chest pain, significant diarrhea, jaundice, or severe abdominal pain requires urgent medical assessment.

Patients should never discontinue treatment or take medication for side effects without consulting their treating team.

Regular follow-ups, laboratory investigations, and careful monitoring help doctors identify complications early and manage treatment safely.
