Haematological cancers (also known as blood cancers) develop in the cells of the blood, bone marrow, or lymphatic system. Examples include chronic leukaemia types like CML (chronic myeloid leukaemia) and CLL (chronic lymphocytic leukaemia). These cancers are less common and often affect older adults. It’s important for patients to have their care overseen by a multidisciplinary team to ensure the best coordinated treatment.
