side effects of chemo include: | -red urine with Doxorubicin Hcl (24-48 hours)-blue urine with Mitoxantrone (immediate 48 hours)-anorexia, stomatitis, diarrhea, constipation, weitht loss, alopecia, fatigue, anemia, leukopenia, thrombocytopenia, chemobrain, tumor lysis, peripheral neu |
TLS | Tumor lysis syndrome. A sudden, rapid breakdown of cells in response to therapy. |
some oncologic emergencies include: | TLS, hypercalcemia, SIADH, pericardial effusion, spinal cord compression, and superior vena cava syndrome. |
pericardial effusion | fluid in ther pericardical cavity, between the visceral and the parietal pericardium. |
If cancer returns how do the goals change? | The plan is for pallative care rather than curative care at this point. |
Alternative Therapy For Cancer: | distraction, massage, biofeedback, guided imagery, reiki, acupuncture, prayer. |
Cancer Prevention: | Primary Prevention of cancer consists of changes on lifestyles to eliminate or reduce exposure to carcinogens. |
Tolerance: | Getting used to the dose, use this word instead of addiction. |
