Elders are more at risk from cancer than others. The incidence of cancer increases with advancing age.  The statistics of cancer in seniors is indeed alarming.
Statistics of cancer in seniors
  • Cancer occurs 10 times more often in elders above 65 than in those younger than this age. 
  • The death rate due to cancer is 16 times more in patients above 65 than the younger ones.
  • Seniors above 65 account for 60% of the malignancies and 70% of the cancer deaths. 
  • Out of every 100 people diagnosed with cancer, 89 are above 50 years.
Why is cancer so prevalent among elders?
Waning vitality, mitigated metabolism and declining immunity are the outcomes of old age and these have damaged the cells in the elderly. These damaged cells may not be repaired by the body owing to old age. When these damaged cells build up, they form cancerous tissues. Poor lifestyle habits and genetic factors also contribute to the early incidence of cancer in the elderly.

However, there is no reason to panic as awareness of the common types of cancer in seniors and their early detection and treatment can achieve a quick cure and better survival from this disease.
