Cancer Flashcards
Tumours (neoplasms) can be benign only.
True / False?
False.
Can be
benign (stay within host structure)
or
malignant (invade local tissues n structures)
Cancer is a type of neoplastic cell development and proliferation in which cells reproduce outside the bounds of normal tissue controls.
True \ False?
True.
What are the differences between benign and malignant tumours?
Benign:
- contained within capsule
- do not spread to distant sites
- usually slow in growth
Malignant:
- metastasize thru body cavities & other structures
- replicate more rapidly n frequently
- able to develop independent blood supply
Cancers which metastasize via blood circulation are less lethal than those that that go through lymph.
True / False?
False.
They are MOrE lethal than those of lymph.
Treatment of both is essential though.
What are some of the treatment options for cancer?
- SURGERY (May be for manageability of other treatments or for comfort during palliative care)
- RADIATION (renders cells sterile, marked by ink/tattooed, causes painful burns to skin)
- CHEMOTHERAPY (sterilize cells via chemical agents or toxins-orally, intravenous, intra arterial or intramuscular)
How is chemotherapy different from radiation?
Chemo causes no superficial skin burns.
10-14 days post surgery it is ok to put drag on tissues when treating cancer patient.
True / False.
False.
No drag and caution must be taken not to infect healing tissues. No on site work unless healing successful as per oncologist.
What is the rule of thumb time frame for considering someone cancers free?
5years symptom free.
Working on scars has to be cautioned as may dislodge trapped malignant cancer cells.
Radiation may continue to damage localized site even after treatment has stopped.
True / False?
True.
Powders, lotions and oils are allowed for treatment post radiation.
True / False?
False.
On site work STRICtLY prohibited if oncologist says so or if they allow tx, only specific powders may be permitted.
How long is I site work prohibited post radiation?
During ‘on’ phase and 2-3 days after.
Can radiation cause arthritic or osteoporotic changes to localized underlying tissues?
Yes.
Which mode of radiation therapy prohibits the patient from receiving treatment due to its exposing the therapist as well?
Radiotherapy device.
Massage decreases metabolic activity of toxic agents thus making patient feel much better.
True / False?
False.
Increases toxic metabolism thus increases potential of making patient feel ill, fatigued and taxing vital organs.
