biology of lymphomas

rat of cellular proliferation is determiendby the specific mutations. A lymphoma driven by a mutation in maturation and prolaiferation will grow quickly and may kill faster, whereas one where apoptosis is blocked will grow a lot slower.
Term
evaluation oflymphoma

get a biopsy, stage the patient (to figure out progrssion of disease), and evlauate vital organ function (especially before giving treatment to make sure that you dotn give the m drug that is supertoxic to something that is already impaired!!,
