Treatment depends on tumor stage, with small tumors least likely to have spread making them the best surgical candidates.

The traditional tumor staging system (TNM classification) provides limited prognostic information, and does not predict response to therapy.

In melanoma, they can be used to determine tumor stage, diagnosis, therapy selection and when to monitor for disease recurrence.

The new edition for the tumor staging system has numerous updates, including building up the prognostic stage group of tumors for the first time and adding a large number of non-anatomical factors into the prognostic evaluation.

Once a diagnosis of TCC is made, it is important to determine the extent of the tumor, i.e. to perform «tumor staging».

Lifespan following the discovery of a malignant mammary tumor depends on many things such as the type of tissue involved (ducts or connective tissue in the breast), the grade of the tumor (how dissimilar the tumor cells are from normal cells when viewed under a microscope), the tumor size (smaller than 3 cm is best), and the tumor stage (whether or not there are metastases and where they are located — regionally or scattered throughout the body).

The outcome for patients with malignant mammary gland tumors depends on several factors including tumor type, histologic grade (appearance of the tumor cells under the microscope and how similar or dissimilar they are to normal tissues), tumor size, and tumor stage (presence of regional and distant metastasis).

Any type of prognosis for the effectiveness of treatment and the future of the disease depends upon different and varying criteria including a tumor's resistance to treatment, the cell type of the tumor, tumor stage and size, and how much the tumor has progressed prior to detection.
