Editing Mastectomy (section)

==Side effects==
Aside from the post-surgical pain and the obvious change in the shape of the chest and/or breast(s), possible side effects of a mastectomy include soreness, scar tissue at the site of the incision, short-term swelling, phantom breast pain (pain in the breast or tissue that has been removed), wound infection or bleeding, hematoma (buildup of blood in the wound), and seroma (buildup of clear fluid in the wound). If the lymph nodes are also removed, additional side effects such as lymphedema (swelling of the lymph nodes) may occur.<ref name=":9">{{Cite web |date=2021-08-08 |title=Mastectomy |url=https://www.hopkinsmedicine.org/health/conditions-and-diseases/breast-cancer/mastectomy |access-date=2022-09-12 |website=www.hopkinsmedicine.org |language=en}}</ref>

Upper limb problems such as shoulder and arm pain, weakness, and restricted movement are a common side effect after breast cancer surgery.<ref>{{Cite journal |last1=Lee |first1=Teresa S. |last2=Kilbreath |first2=Sharon L. |last3=Refshauge |first3=Kathryn M. |last4=Herbert |first4=Robert D. |last5=Beith |first5=Jane M. |date=26 September 2007 |title=Prognosis of the upper limb following surgery and radiation for breast cancer |url=http://link.springer.com/10.1007/s10549-007-9710-9 |journal=Breast Cancer Research and Treatment |language=en |volume=110 |issue=1 |pages=19–37 |doi=10.1007/s10549-007-9710-9 |pmid=17899373 |s2cid=24976113 |issn=0167-6806}}</ref> According to research in the UK, an exercise programme started 7–10 days after surgery can reduce upper limb problems.<ref>{{Cite journal |date=2022-09-26 |title=Exercise programme improves arm function and pain after breast cancer surgery |url=https://evidence.nihr.ac.uk/alert/exercise-programme-improves-arm-function-pain-after-breast-cancer-surgery/ |journal=NIHR Evidence |type=Plain English summary |language=en |publisher=National Institute for Health and Care Research |doi=10.3310/nihrevidence_53632|s2cid=252562000 }}</ref><ref>{{Cite journal |last1=Bruce |first1=Julie |last2=Mazuquin |first2=Bruno |last3=Mistry |first3=Pankaj |last4=Rees |first4=Sophie |last5=Canaway |first5=Alastair |last6=Hossain |first6=Anower |last7=Williamson |first7=Esther |last8=Padfield |first8=Emma J |last9=Lall |first9=Ranjit |last10=Richmond |first10=Helen |last11=Chowdhury |first11=Loraine |last12=Lait |first12=Clare |last13=Petrou |first13=Stavros |last14=Booth |first14=Katie |last15=Lamb |first15=Sarah E |date=February 2022 |title=Exercise to prevent shoulder problems after breast cancer surgery: the PROSPER RCT |url=https://www.journalslibrary.nihr.ac.uk/hta/JKNZ2003 |journal=Health Technology Assessment |language=en |volume=26 |issue=15 |pages=1–124 |doi=10.3310/JKNZ2003 |pmid=35220995 |s2cid=247157545 |issn=1366-5278|doi-access=free }}</ref>
