Overview
Lichen Planus
Lichen planus is an inflammatory condition that can affect the skin, mouth, nails, scalp, or genital areas. It often causes small, itchy, or painful lesions that may appear suddenly or develop gradually. The condition is not contagious and may persist for months or longer. The appearance of lichen planus varies depending on the body area involved. Skin lesions are often purplish, flat-topped, and intensely itchy, while lesions inside the mouth may appear as white lines or patches and can sometimes be painful. Nail, scalp, or genital involvement can require additional assessment. Symptoms may improve over time but can recur.
Breast Cancer
Breast cancer develops when abnormal breast cells grow without normal control. Common invasive types begin in the milk ducts or milk-producing lobules and extend into surrounding tissue. It occurs mainly in women but can also affect men. Possible changes include a lump, thickening, altered breast shape, or nipple discharge; some cancers cause no obvious symptoms.

Lichen Planus
Diagnosis is based on the appearance and location of the lesions and the medical history. A healthcare professional may examine the skin, mouth, nails, or other affected areas. A skin biopsy may be performed when the diagnosis is uncertain or another condition needs to be excluded. A clinician may inspect the distribution, color, shape, and surface of lesions and ask about medications and associated symptoms. Oral lesions may require examination of the gums, cheeks, tongue, and other mucosal surfaces. Biopsy findings can support the diagnosis when clinical features are atypical.
Breast Cancer
Screening looks for cancer before symptoms appear; diagnostic evaluation investigates symptoms or an abnormal screening result. Evaluation may include examination, diagnostic mammography, ultrasound, or MRI when appropriate. A biopsy examines tissue to confirm cancer. After confirmation, tests assess tumor characteristics, including hormone receptors and HER2, and determine the extent of disease.
Prevention
Lichen Planus
There is no guaranteed way to prevent lichen planus because its exact cause is uncertain. Avoiding known triggers or medicines that have previously caused reactions may reduce recurrence in some people. Regular dental care and avoidance of irritating oral products can help when the mouth is affected. Prevention is mainly focused on reducing known aggravating factors because the underlying cause is uncertain. People who develop lichenoid reactions after a medication should discuss alternatives with their healthcare professional rather than stopping prescribed treatment independently. Gentle skin and oral care can reduce irritation in affected areas.
Breast Cancer
Risk reduction cannot guarantee prevention. Limiting alcohol, maintaining a healthy weight, and being physically active may reduce risk. People with a strong family history or known inherited susceptibility can discuss genetic assessment and appropriate risk-reduction options with a healthcare professional. Screening is intended to detect cancer early; it does not prevent cancer from developing.
Risk Factors
Lichen Planus
Risk factors for lichen planus may include certain medications, hepatitis C infection, immune-system abnormalities, and other triggers. It can occur at any age but is more common in adults. Some people may also develop the condition after exposure to specific substances or treatments. Some people with lichen planus have associated autoimmune or inflammatory conditions. Certain medicines can produce lichenoid reactions, and hepatitis C has been associated with the condition in some populations. Oral disease may be influenced by local irritation, dental materials, tobacco exposure, or other factors, although these associations do not mean that they cause every case.
Breast Cancer
Risk increases with age. Other factors include a personal history of breast cancer or certain breast conditions, family history, inherited susceptibility, and dense breasts. Hormonal and reproductive history can influence risk. Alcohol use, excess weight after menopause, and physical inactivity are also associated with increased risk. Having a risk factor does not mean cancer will develop.
