This is an advanced and modern test aimed at evaluating and analyzing genes from the cancer cells. In this test a sample of breast cancer tissue is taken usually an early stage cancer is preferred, 70 genes are isolated from this sample and analyzed. This analysis is done for assessing the recurrence risk of the cancer within span of 10 years post diagnosis and detection. The results of mammprint test are quite useful and if the results are comprehended in relation to other aspects of cancer can be utilized in prescribing treatment. The results can tell us if chemotherapy radiations or what other course of therapy should be undertaken.
This test can specifically be put to use for analysis of breast cancers in early stages. It is used on stage I and stage II cancers, cancers which are invasive, growth of cancerous cells which is smaller than 5 centimeters, testing of estrogen-receptor-positive or -negative quality of the tumor growth. Also for cancers which have spread to three or lesser number of lymph nodes, this test can be undertaken.
Also the tissue to be analyzed for the MammaPrint test can be fresh or freshly frozen or even it may be treated or "fixed" tissue. In it with special treatment of certain chemicals, the genetic material is preserved.
This test analyses 70 genes of the body which have closest relationship with the breast cancer tissue and by this analysis, it is able to determine the recurrence probability of the cancer within a span of 10 years post treatment.
The results may be announced as high risk or a low risk result. A low risk result would mean that the recurrence risk of the cancer within 10 years is at 10% without the administration of any additional therapy apart from original. Now with hormonal therapy this risk can be lowered to 5%. A high risk result would mean that the recurrence risk of the cancer within 10 years is at 29% without the administration of any additional therapy.
