Precision oncology is a modern approach to cancer care where treatment decisions are guided by the specific features of a patient’s cancer. Instead of treating every cancer only by its organ of origin, precision oncology looks deeper into the tumor’s molecular and genetic profile.

Every cancer can have a unique pattern of biological changes. Biomarker testing can identify genes, proteins, or other markers that may help doctors choose a more suitable treatment plan.

Why Is Biomarker Testing Important?

Biomarker testing may help answer important questions such as:

• Is this cancer likely to respond to targeted therapy?
• Is immunotherapy suitable?
• Are there genetic or molecular changes driving the cancer?
• Should treatment be adjusted based on the cancer’s biology?
• Is the patient eligible for a specific advanced treatment option?

This is especially relevant in cancers such as lung cancer, breast cancer, colorectal cancer, and some gynecologic or genitourinary cancers.

Targeted Therapy and Immunotherapy

Targeted therapy works by focusing on specific proteins or pathways that help cancer cells grow, divide, and spread. It is one of the foundations of precision medicine.

Immunotherapy is different. It helps the body’s immune system recognize and fight cancer more effectively. Some cancers can hide from immune attack, and immunotherapy may help restore the immune system’s ability to respond.

Does Every Patient Need Precision Oncology?

Not every patient needs every advanced test. The decision depends on cancer type, stage, available tissue sample, previous treatment history, symptoms, general health, affordability, and available treatment options.

This is why precision oncology should be guided by a cancer specialist. A test is useful only when it can help make a practical treatment decision.

Precision Oncology in Bangladesh

For patients in Bangladesh, precision oncology is becoming increasingly important, but access to advanced molecular testing and some newer treatments may still vary. A specialist can help patients understand which tests are necessary, which are optional, and which results can realistically guide treatment.

Dr. Muhammad Rafiqul Islam’s website strongly emphasizes precision oncology, clinical research, cancer genetics, molecular analysis, targeted therapy, immunotherapy, and evidence-based treatment planning.

If you or a family member has been diagnosed with cancer and wants to understand whether biomarker testing, targeted therapy, or immunotherapy may be relevant, book a consultation for a personalized oncology review.

Medical note: Precision oncology does not guarantee a cure, and not every patient is eligible for targeted therapy or immunotherapy. Treatment decisions must be made after specialist evaluation.
