Carcinoma in situisabnormal cell growth in the tissue lining an organ. This growth is generally limited to these networks. But if left unchecked, this collection of abnormal cells can grow and develop into cancer, then spread to normal tissue in the bodysurroundings.
Carcinoma in situ is a condition that is closely related to cancer. In medical terms, carcinoma in situ considered as the earliest stage or stage 0 of cancer. This stage can be found in some types of cancer and certain organ surfaces.
Multiple Kinds Carcinoma In Situ
The following are some types carcinoma in situ frequently found:
1. Ductal Carcinoma In Situ
Ductal carcinoma in situ (DCIS) are abnormal cells that appear on the surface of the milk ducts in the breast. DCIS is considered to be the earliest form of breast cancer. DCIS is noninvasive which means it has not spread beyond the milk ducts and invades other breast tissue.
Although not an emergency, DCIS still requires treatment to prevent it from becoming malignant, for example with a mastectomy or lumpectomy. See a doctor immediately if you notice any changes in your breasts, such as the appearance of a lump in the breast or a discharge with blood from the nipple.
2. Lobular Carcinoma In Situ
Lobular carcinoma in situ (LCIS) or also known as lobular neoplasia are cells that look like cancer cells on the surface of the mammary glands (lobules). LCIS is not considered cancer. However, LCIS can increase the risk of developing breast cancer.
Women with LCIS have an approximately 7–12 times higher risk of developing malignant cancer in both breasts. Therefore, women with LCIS need to undergo regular breast cancer screening on a regular basis to monitor the development of the LCIS condition.
3. Cervical Carcinoma In Situ
Cervical carcinoma in situ are abnormal cells that appear on the surface of the cervix or cervix and have not penetrated deeper into the surrounding tissue. Cervical carcinoma in situ considered as the earliest stage of cervical cancer which is usually caused by human papillomavirus (HPV).
Cervical carcinoma in situ usually cause no symptoms. However, this condition can generally be easily found with early detection of cervical cancer, for example with VIA and Pap smears. Cervical cancer screening is recommended for women aged 21–65 years, especially those who are sexually active.
4. ColorectalCarcinoma In Situ
Colorectal carcinoma in situ is a collection of abnormal cells found in the mucosa or lining of the inner wall of the large intestine or rectum. These abnormal cells are the earliest stage of colorectal cancer, so they need to be treated early if found.
As well as carcinoma in situ in the cervix, stage 0 colorectal cancer is often asymptomatic. Therefore, people with a higher risk of developing this cancer, for example people with a history of colon polyps, are advised to get screened regularly.
5. Nasopharyngeal Carcinoma In Situ
Nasopharyngeal carcinoma in situ are abnormal cells that grow on the surface wall of the nasopharynx, which is the area of the nose and back of the mouth. As carcinoma in situ others, other tissues in the area of the nasopharynx or surrounding lymph nodes are not affected and are still in good health.
Although not yet spread, nasopharyngeal carcinoma in situ is the earliest stage of nasopharyngeal cancer. So, abnormal cells are more likely to develop into malignant cancer if left untreated.
6. Squamous cell carcinoma in situ
Squamous cell carcinoma in situ Also known as Bowen's disease, it is the earliest form of skin cancer or squamous cell carcinoma. Squamous cell carcinoma in situ Usually characterized by red, scaly patches on the skin that are often exposed to sunlight.
Although not all will definitely develop into cancer, the existence of carcinoma in situ should be aware. Therefore, most people who experience it will be advised to immediately undergo treatment, if possible.
This is because the lower the stage of cancer when treated, usually the higher the success rate. Handling can be in the form of chemotherapy drugs, radiation therapy, to surgery.
Even if treatment carcinoma in situ cannot be done, this condition needs to be monitored regularly by a doctor. Patients will also be advised to be more active in implementing a healthy lifestyle to reduce the risk of cancer.
Carcinoma in situ can be found by screening. You can consult a doctor about your medical history and what cancer screenings you think you need to do. You can also consult about handling carcinoma in situ if this condition is found on examination.
