In people with cancer, strong opioid painkillers do not differ from each other for pain relief or side effects
Schmidt-Hansen M, Bennett MI, Arnold S, et al. Oxycodone for cancer-related pain. Cochrane Database Syst Rev. 2015;2:CD003870.
Review question
In people with cancer, does oxycodone reduce pain better than other strong painkillers?
Background
People with cancer often have pain. Opioids, including oxycodone, are strong painkillers that are often prescribed for cancer pain. Oxycodone can be taken by mouth as immediate-release tablets or liquid (taken every 4 hours) or as controlled-release tablets (taken every 12-hours). Opioids do not reduce pain for all people, and they can have side effects.
How the review was done
The researchers did a systematic review, searching for published studies up to March 2014. They found 7 randomized controlled trials of 1390 people (average age 45 to 69 years).
People in the trials were 18 years of age or older and had pain related to cancer.
Oxycodone was compared with another dose or form of oxycodone, another active drug, or placebo.
What the researchers found
The quality of the evidence was low.
Controlled-release oxycodone and immediate-release oxycodone did not differ for pain relief in 3 of 3 trials or side effects in 3 of 4 trials.
Oxycodone and morphine did not differ for pain relief or side effects.
Other formulations of oxycodone and other opioids also did not differ for relief of pain or side effects.
Conclusion
In people with cancer, oxycodone does not differ from other strong opioids, including morphine, for relief of pain or side effects.
Oxycodone vs another dose or form of oxycodone or another active drug in people with cancer-related pain
Controlled-release vs immediate- release oxycodone | 3 trials (578 people) | No difference in pain or side effects |
Oxycodone vs morphine | 5 trials (462 people) | No difference in pain or side effects |

Your risk of dying from breast cancer is slightly reduced if you have regular screening. However, regular screening increases your chance of a false positive result, a biopsy and having part or all of a breast removed unnecessarily.

Canadian Task Force on Preventive Health Care
The Canadian Task Force on Preventive Health Care recommends women between 50 and 74 years old who are not at high risk get screened for breast cancer every 2 to 3 years. Talk to your doctor about screening options if you are at high risk or over 74 years old.
