Geriatric oncology is that the concept for management of elderly cancer patients. Therefore its not a subspecialty but a practice which may be translated within the elderly cancer patients care. The treatment of cancer is predicated on equivalent principles than this of younger patients; recommendations used are those of the scientific oncological societies. Health problems of elderly patients are screened by specific tools. Patients without major health problems are managed by the oncological team within the routine; those for whom screening have demonstrated problems are first evaluated within the geriatrics setting then oncological decisions are adapted to the patient situation. Decisions are made in specific geriatric oncology conferences. Specific clinical trials are required to create an Evidence Based Medicine background. Geriatric oncology teaching programs are warranted. The cellular and molecular mechanisms regulating the physiological process of ageing and senescence are far away from understood, although inflammation is probably going to play a crucial role, a minimum of in some cancers. Additionally, the connection between ageing and cancer risk is additionally faraway from understood. One among the foremost intriguing aspects of ageing is how different the ageing process is from person to person; the idea for this variation is essentially unknown. Population-based studies and longitudinal surveys have shown that comorbidity and physical and mental functioning are important risk factors; thus, a meaningful assessment of comorbidity and disability should be implemented in clinical practice. Modern geriatrics is targeted towards patients with multiple problems.
