What stage is a 2 cm tumor?

In stage I, the tumor measures up to 2 cm and no lymph nodes are involved. At this stage, the cancer cells have spread beyond the original location and into the surrounding breast tissue. Because a stage I tumor is small, it may be difficult to detect.

What are the characteristics of a malignant tumor?

A malignant neoplasm is composed of cells that look less like the normal cell of origin….Thus, characteristics of malignant neoplasms include:More rapid increase in size.Less differentiation (or lack of differentiation, called anaplasia)Tendency to invade surrounding tissues.Ability to metastasize to distant tissues.

Is a malignant tumor curable?

However, malignant tumours will often eventually return after treatment. If this happens, or if you have a secondary tumour, a cure isn’t usually possible and treatment can instead be used to improve symptoms and prolong life. Read more about treating malignant brain tumours.
