Such tissues include the skin, testis, ovaries, breast, uterus, liver, spleen, gastro-intestinal tract, growing bones, blood cell, lungs, lymph nodes etc. The commonest cancers therefore involve the lungs (carcinoma), blood (leukemia), lymphoid tissues (lymphoma), bones (osteoma or steosarcoma), skin (carcinoma), liver (hepatoma), ovaries (cystadenoma or cystadenocarcinoma). buy viagra without prescription The destructive potential of a particular cancer depends on the type and location.
