a and b only

Explanation:

• Question 7: Carcinomas specifically arise from epithelial tissues that line internal and external body surfaces, while leukemias are blood/bone marrow cancers, osteomas are bone tumors, and sarcomas develop in connective tissues.
• Question 8: Acute pain is defined as pain with a recent, sudden onset, in contrast to chronic pain which lasts 6+ months. Acute pain typically signals tissue damage, so it has a protective purpose, and it can usually be linked to a specific cause.
• Question 9: Radiation therapy is a common cancer treatment used by many patients, often alone or with surgery, chemotherapy, etc. It does have notable side effects, so the only correct statement is that it can be used alone or in combination.

Answer:

1. Question 7: D. Carcinomas.
2. Question 8: D. Is recent in onset.
3. Question 9: B. May be used alone or in combination with other treatments.
