Cancer Runs in Families Too - GKNM's Cancer Genetics Clinic Can Help
When cancer strikes a family, it often brings not only medical challenges but also fear, uncertainty, and questions about the future. "Will this affect my children?" "Am I at risk too?" These are concerns many families silently carry.
While most cancers happen by chance, about 5-10% are hereditary. This means an altered gene, passed from parent to child, increases the risk of certain cancers. In such families, cancers may occur at a younger age or affect more than one member.
The Cancer Genetics Clinic at GKNM Hospital, Coimbatore, was set up to help families find answers. The clinic offers genetic testing, a simple but powerful tool that can show whether someone carries a cancer-related gene mutation. More importantly, it provides guidance and support -from regular check-ups and early screening to preventive strategies that safeguard both the individual and their loved ones.
You may benefit from genetic testing if:
- Cancer was diagnosed at a young age (under 50 years).
- Two or more close relatives have the same or related cancers.
- A person has had two different primary cancers.
- A family member has had a rare cancer linked to inherited syndromes.
- A known genetic mutation has already been identified in the family.
Why this matters
Knowing your risk is not about living in fear-it's about living with confidence. Genetic testing can give families clarity, protect children and future generations, and allow doctors to detect cancers earlier, when treatment works best.

Planning on having surgery soon? Or cancer treatment? Just want to know where to get help in case your family has an emergency? In any case, you want to know which hospital is best and nearest to you. Many sites now rate hospitals. Knowing how they're set up and understanding what you can rely on them for -- and not -- is key to using them successfully.

Dr. Arul Raj is phenomenal. I had to undergo a Thyroidectomy for which I consulted him. He suggested Robotic Surgery, and I appreciate how thoroughly he explained everything to me; He patiently addressed all my queries, which helped me understand my medical issue. Not only is Dr. Arul Raj beyond caring, but he also made sure that I was comfortable and happy during my stay in the hospital post-surgery. I couldn't ask for a better doctor to put my trust in. I highly recommend him for Oncological surgeries.
