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.
Colon Cancer
Colon cancer is a malignant growth that develops in the lining of the colon, part of the large intestine. It often begins as a polyp or other abnormal growth that can gradually develop into cancer over time. Early colon cancer may cause few or no noticeable symptoms. Possible symptoms include changes in bowel habits, blood in the stool, abdominal discomfort, unexplained weight loss, weakness, or anemia caused by chronic blood loss. Screening can identify some precancerous polyps and cancers before symptoms appear, while diagnosis and staging help determine the appropriate treatment approach.

Diagnosis

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.
Colon Cancer
Colon cancer may be detected through screening tests such as stool-based testing or colonoscopy, depending on age, risk, and applicable screening recommendations. When cancer is suspected, colonoscopy allows direct examination of the colon and removal or biopsy of abnormal tissue. A biopsy is used to establish the diagnosis of cancer. Additional imaging and laboratory evaluation may be performed to determine the stage of disease and whether it has spread to lymph nodes or other organs.

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.
Colon Cancer
The risk of colon cancer may be reduced through recommended colorectal cancer screening, avoiding tobacco, limiting excessive alcohol use, maintaining a healthy body weight, staying physically active, and following a balanced dietary pattern. Screening is particularly important because precancerous polyps can sometimes be detected and removed before they become cancer. People with a family history, inherited cancer syndrome, inflammatory bowel disease, or other increased-risk conditions may require a different screening approach based on medical advice.

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.
Colon Cancer
Risk factors for colon cancer include increasing age, a personal or family history of colorectal cancer or certain polyps, inherited cancer syndromes, inflammatory bowel disease, smoking, heavy alcohol use, physical inactivity, and certain dietary patterns. Excess body weight and metabolic health factors may also be associated with increased risk. Risk is influenced by multiple factors, and colon cancer can occur in people who do not have an obvious risk factor.
