A primary care physician is important for cancer survivors for several reasons: 1) Primary care physicians can provide whole person care beyond just cancer, including preventative care, management of other health conditions, and annual checkups. 2) Oncologists focus narrowly on cancer care while primary care physicians take a broader view of patient health. 3) More patients have access to primary care physicians than oncologists, and primary care physicians can help coordinate care between specialists like oncologists. 4) Establishing care with a primary care physician and having a survivorship care plan facilitates smooth transitions in care after cancer treatment is completed.
