differentiate‚ to continue to look like the mother cell poorly differentiated‚ on the chart‚ means that the cells in the tumor have gone through so many mutations that they no longer look like or function like the original tissue‚ example: uterine carcinoma‚ they don’t look or function like the original cells of the uterus more importantly it means they do not respond to treatment well‚ resistant to treatment so poorly differentiated is a bad thing malignancy and benign both are tumors‚ or

Radioisotopes are radioactive isotopes of an element. An isotope is an element’s atom that has the same number of protons and electrons‚ but a different number of neutrons‚ causing the atom to be unstable. With radioisotopes‚ they can occur naturally‚ but most often are formed artificially by altering the atom. Scientists measure the rate of which radioisotopes decay at by using the term half-life. This refers to when one-half of the radioactive material has decayed. When the word radioactive comes

Three months after her early treatment‚ she was diagnosed with lymph node metastases on her right groin which means her disease has spread and cannot be cured. Jennifer will now be in palliative

It is important to detect cancer as soon as possible
