A doctor has outlined the red flag signs of a type of blood cancer, known as Hodgkin’s lymphoma, that affects the white blood cells which are called lymphocytes.

Also called the cancer of the lymphatic system, Hodgkin’s lymphoma targets a network of vessels and glands spread throughout your body, which form a part of the immune system that helps to fight off infections.

Dr James O’Donovan warned that symptom awareness is crucial as finding cancer early means it’s easier to treat.

Fortunately, the medical expert took to his YouTube channel to share what to look out for.

The first tell-tale sign of Hodgkin’s lymphoma is a painless swelling in the lymph node, which can appear in your neck, armpits or the groin.
