Final answer:
Primary care best describes early detection, routine care, and prevention, focusing on integrated healthcare services for various health needs, which may include cancer diagnosis through routine screening and biopsy.
Step-by-step explanation:
The best description of primary care is early detection and routine care, as well as prevention. Primary care involves the provision of integrated and accessible health care services by clinicians who are accountable for addressing a large majority of personal health care needs, developing a sustained partnership with patients, and practicing in the context of family and community.
Primary care services include diagnosing cancer which requires early detection often through routine screening. Once a potential cancer is detected, a definitive diagnosis usually requires a biopsy before treatment can begin. Treatments for cancer can include surgery, chemotherapy, radiation therapy, and immunotherapy, depending on the type and stage of cancer.
