The month of May is designated for heightened awareness of multiple types of cancers. The principle behind cancer awareness is to make the public aware of specific symptoms that may warrant targeted medical evaluations. And to emphasise about cancer screening tests that are aimed at early detection of cancer, with prompt treatment that may enhance chances of cure.
Many cancers present themselves through screening and early detection. Examples include breast cancer, prostate cancer, cervical cancer, colon cancer and many more. Cancer specialists in conjunction with public health authorities, usually provide scientifically sound guidelines on cancer screening strategies. Such guidelines include specific age groups and testing modalities (think imaging, blood tests and biopsies). Crucially, cancer screening guidelines also advise against testing in specific circumstances.
