Diagnosis of cancer History:  Exposure (at work place, home, travel): asbestos, pesticides,  Any growths, lumps  Bleeding or blood in sputum, stool, urine  Change in bowel or bladder habits, visible moles  Discharge: breast, vaginal, intestinal  Hoarseness of the voice  Indigestion or difficulty swallowing  Nagging cough or Examination:  Inspection:  Obvious changes in a wart or a mole  Sores that doesn’t heal  Anemia and hypoxia; clubbing nails (fingers)  thromboflebitis in other vessels than leg veins  Ausculatation:  Lung  Abdomen: obstruction  Palpation:  any growth or lump  Lymph nodes at JOINTS  Tissue firmness Laboratory Diagnosis of Cancer  Histological  Cytological sample: Papanicolaou smear  Fine needle aspiration: a thin (23–25 gauge (0.52 to 0.64 mm outer diameter)), hollow needle is inserted into the mass for sampling of cells → stained →microscopic examination (biopsy).  Quick-frozen section: during surgery  Biopsy  Biochemical assays o Prostate specific antigen o Human chorionic gonadotrophin o Catecholeamine metabolites  Receptor analysis  Tumor antigens  Tumor specific antigens o MAGE-1-melanoma associated antigen-1  Tumor associated antigens (for the tissues) Dr M Hossu Notes 165  o Prostate specific antigen o Carcinoembryonic antigen o Alpha-fetoprotein o Virus associated antigens  in most cases transformed cells lose normal antigens and do not necessarily express new ones Treatment of Malignancy  N.B. The treatment of malignancy is not usually an emergency, o so there is usually time to gather information. o A well informed patient is extremely important. o Record all info and keep a journal. o Mental and emotional stress & support needed  Surgery  Radiation  Chemotherapy  Molecular therapies (modern monoclonal antibodies, cytokines)  Alternative immune stimulation o PAMP / TLR o Hyperthermia o miRNA o Spontaneous remission  Cen X., Liu S., Cheng K.
