Breast diseases make up a number of conditions. The most common symptoms are a breast mass, breast pain, and nipple discharge.{{cite journal |last1=Salzman |first1=B |last2=Fleegle |first2=S |last3=Tully |first3=AS |title=Common breast problems. |journal=American Family Physician |date=15 August 2012 |volume=86 |issue=4 |pages=343–9 |pmid=22963023}}

A majority of breast diseases are noncancerous.{{cite web |url=https://www.nlm.nih.gov/medlineplus/breastdiseases.html |title=MedlinePlus: Breast Diseases |access-date=2018-03-21 |archive-date=2016-07-05 |archive-url=https://web.archive.org/web/20160705055617/https://www.nlm.nih.gov/medlineplus/breastdiseases.html |url-status=live }}

Although breast disease may be benign, or non-life threatening there remains an associated risk with potentially a higher risk of developing breast cancer later on.{{cite web |title=Non-Cancerous Breast Conditions {{!}} Benign Conditions |url=https://www.cancer.org/cancer/types/breast-cancer/non-cancerous-breast-conditions.html#:~:text=Benign%20(non%2Dcancerous)%20breast,getting%20breast%20cancer%20later%20on. |website=www.cancer.org |language=en}}

A breast tumor is an abnormal mass of tissue in the breast as a result of neoplasia. A breast neoplasm may be benign, as in fibroadenoma, or it may be malignant, in which case it is termed breast cancer. Either case commonly presents as a breast lump. Approximately 7% of breast lumps are fibroadenomas and 10% are breast cancer, the rest being other benign conditions or no disease.Page 739 in: {{cite book |author1=Mitchell, Richard Sheppard |author2=Kumar, Vinay |author3=Abbas, Abul K. |author4=Fausto, Nelson |title=Robbins Basic Pathology|year=2007 |publisher=Saunders |location=Philadelphia |isbn=978-1-4160-2973-1 }} 8th edition.

Phyllodes tumor is a fibroepithelial tumor which can be benign, borderline or malignant.

=Breast cancer=

Breast cancer is cancer of the breast tissues, most commonly arising from the milk ducts. Worldwide, breast cancer is the leading type of cancer in women, accounting for 25% of all cases.{{cite book|title=World Cancer Report 2014|date=2014|publisher=World Health Organization|isbn=978-92-832-0429-9|pages=Chapter 1.1}} It is most common in women over age 50.

Signs of breast cancer may include a lump in the breast, a change in breast shape, dimpling of the skin, fluid coming from the nipple, a newly inverted nipple, or a red or scaly patch of skin.{{cite web|url=http://www.cancer.gov/cancertopics/pdq/treatment/breast/Patient/page1/AllPages|title=Breast Cancer Treatment (PDQ®)|date=23 May 2014|website=NCI|archive-url=https://web.archive.org/web/20140705110404/http://www.cancer.gov/cancertopics/pdq/treatment/breast/Patient/page1/AllPages|archive-date=5 July 2014|url-status=live|access-date=29 June 2014|df=dmy-all}} Diagnosis may also be made when the cancer is asymptomatic, through breast cancer screening programs, such as mammograms. Outcomes for breast cancer vary depending on the cancer type, extent of disease, and person's age.{{cite web|url=http://www.cancer.gov/cancertopics/pdq/treatment/breast/healthprofessional/page1/AllPages|title=Breast Cancer Treatment (PDQ®)|date=26 June 2014|website=NCI|archive-url=https://web.archive.org/web/20140705110521/http://www.cancer.gov/cancertopics/pdq/treatment/breast/healthprofessional/page1/AllPages|archive-date=5 July 2014|url-status=live|access-date=29 June 2014|df=dmy-all}} Survival rates in the developed world are high,{{cite web|url=http://www.iarc.fr/en/publications/pdfs-online/wcr/2008/wcr_2008.pdf|title=World Cancer Report|year=2008|publisher=International Agency for Research on Cancer|archive-url=https://web.archive.org/web/20110720232417/http://www.iarc.fr/en/publications/pdfs-online/wcr/2008/wcr_2008.pdf|archive-date=20 July 2011|url-status=dead|access-date=26 February 2011|df=dmy-all}} with between 80% and 90% of those in England and the United States alive for at least 5 years.{{cite web|url=http://seer.cancer.gov/statfacts/html/breast.html|title=SEER Stat Fact Sheets: Breast Cancer|website=NCI|archive-url=https://web.archive.org/web/20140703030149/http://seer.cancer.gov/statfacts/html/breast.html|archive-date=3 July 2014|url-status=live|access-date=18 June 2014|df=dmy-all}}{{cite web|url=http://www.ons.gov.uk/ons/dcp171778_333318.pdf|title=Cancer Survival in England: Patients Diagnosed 2007–2011 and Followed up to 2012|date=29 October 2013|website=Office for National Statistics|archive-url=https://web.archive.org/web/20141129124915/http://www.ons.gov.uk/ons/dcp171778_333318.pdf|archive-date=29 November 2014|url-status=live|access-date=29 June 2014|df=dmy-all}}
