Oncology Flashcards
cancer stage 1
early stage - small, invasive mass or tumor identified; no spread to lymph nodes or other tissues
cancer stage 2
localized stage - tumor cells begin to spread to nearby tissue, mass may have grown in size, spread to lymph nodes near the mass
cancer stage 3
regional spread - cancer affects more surrounding tissue, mass may have grown in size, spread to lymph nodes away from the mass
cancer stage 4
distant spread - has spread to other tissues/organs beyond initial location, sometimes called advanced or metastatic cancer
benign
non cancerous
malignant
cancerous
blasts
immature WBCs
lymphoid
tissue that makes lymphocytes
myeloid
tissue of the bone marrow
lymphoma
arises from lymphoid tissue
myeloma
arises from myeloid tissue
carcinoma
arises from the surface or epithelium
sarcoma
arises from the connective tissues
chemotherapy
causes immunosuppression as it kills cancer cells it also destroys health cells, prevents cancer from metastasizing
chemotherapy SE
anemia/fatigue, thrombocytopenia/bleeding risk, neutropenia/immunosuppresion/high infection risk, GI upset/loss of appetite/nausea and vomiting
radiation
high energy directed at cancer cells to shrink and kill them, more localized than chemo, external or internal (brachytherapy, body may give off radiation for short amount of time)
Neutropenic precautions
strict handwashing before client care, no sick visitors or staff, no fresh produce or flowers, private room closed door, no live vaccines, avoid invasive procedures, limit visitation
leukemia
cancer of the blood, progressive disease in which the bone marrow produces increase numbers of immature or abnormal WBCs, this suppresses the production of normal blood cells leading to anemia and other S&S
