Why does cancer get diagnosed so late?

Considerable diagnostic delay might occur if several invasive procedures are needed to confirm the diagnosis and the suitability for surgical treatment. In summary, a delay in cancer diagnosis can occur at various levels. The patient may fail to recognise suspicious cancer symptoms or act on them.

How long does it take to detect cancer?

As an extension of Collins’ law, our graphs of local recurrence data suggest that the typical age of a cancer at diagnosis is approximately 5 to 6 years for breast cancer, and 3 to 4 years for lung cancer and rectal cancer. Financial Disclosure:Dr.

What cancers can go undetected?

Lung cancer, ovarian cancer, colorectal and cervical cancers, as well as breast cancer, can all go unnoticed by patients until they are very advanced, stage 3 or stage 4 tumors. These tumors are often defined as “late stage” cancers.
