My brother was diagnosed with cancer and I would like to have more understanding about the disease. Is early detection possible for cancer ?

Some early signs of cancer include lumps, sores that fail to heal, abnormal bleeding, persistent indigestion, and chronic hoarseness.
Early diagnosis is particularly relevant for cancers of the breast, cervix, mouth, larynx, colon and rectum, and skin.

Screening refers to the use of simple tests across a healthy population in order to identify individuals who have disease, but do not yet have symptoms.
Examples
breast cancer screening using mammography and cervical cancer screening using cytology screening methods

yes, it is possible to identify cancer at an early stage with a proper diagnosing method (physical test, imaging test, laboratrory test, biopsy) and observing for signs and symptoms for cancer.
