Q

skin cancer disease prevention

A
  • Limit exposure to sunlight, especially between 1000 and 1500.
  • Apply sunscreen when near reflective surfaces (sand, snow, water, concrete).
  • Use sunblock that has an SPF of at least 15/20, with both UVA and UVB protection, even in winter months

Q

cause of Leukemias and Lymphomas

A
  • The goal of treatment is to eliminate all leukemic cells.
