What does P mean in staging?
Pathological staging is based on what is found during surgery. Clinical stage is often indicated with a lowercase “c” before the TNM classification. The pathological stage is indicated with a lowercase “p.” In general, pathological staging provides the most information to determine a patient’s prognosis.

p (for “pathological”) means that removed tissue was tested in a laboratory, and that the diagnosis was made based on the results of that test. r (for “recurrence”) means that a tumor has returned. R means that remaining cancer tissue was found after treatment.

In situ—Abnormal cells are present but have not spread to nearby tissue. Localized—Cancer is limited to the place where it started, with no sign that it has spread. Regional—Cancer has spread to nearby lymph nodes, tissues, or organs. Distant—Cancer has spread to distant parts of the body.
How do all cancers begin?
All cancers begin in cells. Our bodies are made up of more than a hundred million million (100,000,000,000,000) cells. Cancer starts with changes in one cell or a small group of cells. Usually, we have just the right number of each type of cell.

How are T, N and M used to determine stage of cancer?
For some cancers, the values for T, N, and M aren’t the only things that determine the stage. Some other factors that may be taken into account include: Grade: For most cancers, the grade is a measure of how abnormal the cancer cells look under the microscope. This is called differentiation.
