• Breast Cysts: Cysts are closed sac-like pockets of tissues that can be tender and lumpy. These cysts do not increase the chances of developing breast cancer.
• Hyperplasia: Hyperplasia is a condition characterised by an increase in the number of breast cells, which leads to their enlargement. 
• Fibroadenomas: Fibroadenomas are the most common solid, non-cancerous lumps usually found in young women and require no treatment. 
• Fibrocystic Breast Changes: This type of breast disease is characterised by pain, swelling, and lumps in the breasts, often fluctuating with the menstrual cycle.
• Mastitis: Mastitis is another common condition resulting in inflammation of the breast tissues usually caused by a blocked milk duct or infection.
• Adenosis: Adenosis is caused when the lobules (milk-producing part of the breast) grow larger and contain more glands than usual.

Although benign breast diseases do not pose a threat to life some of them may raise the chance of breast cancer in the future. Furthermore, early detection and treatment are critical for several reasons including: 

• Rule Out Cancer: Early detection helps rule out malignant disease as some benign conditions can mimic breast cancer in symptoms. 
• Avoid Complications: Certain benign diseases if left untreated can worsen over time and lead to complications including pain, scarring, and infection. 
• Identify Risk Early: Certain types of benign breast disease like atypical hyperplasia, are associated with increasing the risk of developing breast cancer in the future. Early detection helps identify abnormal changes & manage them effectively.
• Relieve Symptoms: Several types of benign breast disease are known to cause discomfort, pain, tenderness, and visible lumps. Early detection & treatment help manage these symptoms effectively.

• Hormonal Fluctuations: Fluctuations of hormones during menstruation cycles can affect breast tissues resulting in lumps.

• Breast Infections: Infections causing inflammation of breast tissues due to blocking of breast milk ducts or bacterial infections can lead to lumps or tenderness.
• Fibrocystic Changes: Benign breast disease can also be caused by changes in breast tissues resulting in the formation of cysts and fibrous areas that may feel like lumps.
• Injuries: Trauma or injury to the breast can also lead to the formation of cysts or fat necrosis (a condition where fatty tissues in the breast die).

Several factors may increase the risk of developing benign breast disease including:

• Family History: A family history of benign or malignant breast disease particularly in first-degree relatives increases the risk for developing breast disease.
• Hormonal Factors: A fluctuating oestrogen and progesterone level and the use of oral contraceptives or hormone replacement therapy may influence the development of benign breast diseases.
• Alcohol Consumption: Several studies associate alcohol consumption with an increasing risk of breast diseases, particularly in adolescence.
• Breast Trauma or Surgery: Any previous trauma of breast surgery can increase the risk of developing breast conditions like necrosis or other benign lumps.
• Medications: Certain medications can also increase the risk of developing benign breast diseases like medicines that affect the hormone levels or the pituitary gland can cause breast changes. 

Signs of benign breast disease can be noticed during a self-examination, some of the most common symptoms of benign breast disease include:

• Breast Pain: Generalised or localised pain that worsens before menstruation. 
• Lumps: Smooth, firm, rubbery & painless lumps might appear that are usually painless.
• Nipple Discharge: A milky, clear & dark-coloured discharge may appear.
• Change in Size: Noticeable changes in the size, shape & contour of the breast. 
• Skin Changes: The skin might appear thick and red.
