CIN的手術副作用/後遺症

CIN or, Cervical intraepithelial neoplasia, is the abnormal growth of precancerous cells in the cervix. Most cases of CIN remain stable, or are eliminated by the host's immune system without intervention. However a small percentage of cases progress to become cervical cancer, usually cervical squamous cell carcinoma, or SCC.[1] The major cause of CIN is infection with the sexually transmitted human papillomavirus (HPV), usually the high-risk HPV types 16 or 18.

The earliest microscopic change corresponding to CIN is dysplasia of the epithelial or surface lining of the cervix, which is essentially undetectable by the woman. Cellular changes associated with HPV infection, such as koilocytes, are also commonly seen in CIN. It is usually discovered by a screening test, the Papanicolaou or "pap" smear. The purpose of this test is to diagnose the disease early, while it has not yet progressed to invasive carcinoma, and thus is easy to cure. Though epithelial dysplasia may regress spontaneously, persistent lesions must be removed, either with surgery, chemical burning, heat burning, burning with laser, or freezing (cryotherapy).

CIN1 (Grade I), the least risky type, represents only mild dysplasia, or abnormal cell growth[1] and is considered a low grade squamous intraepithelial lesion (LGSIL). [2]. It is confined to the basal 1/3 of the epithelium.
CIN2 (Grade II), as well as CIN III, are considered high grade squamous intraepithelial lesions (HSIL). [2] CIN2 represents moderate dysplasia, and is confined to the basal 2/3 of the epithelium
CIN3 (Grade III): In this lesion, severe dysplasia spans greater than 2/3 of the the entire epithelium, and may involve the full thickness. This lesion may also be referred to as cervical carcinoma in situ.

手術副作用／後遺症當然就是痛﹐流血﹐分泌多
點都有幾日
仲有麻醉藥的副作用
但長遠黎講就沒有聽人講過了
呢個叫 LEEP cone 的手術是很小的手術﹐很多人做的﹐不用太擔心
但如果不做﹐沒有其他更好的方法﹐如果已經有 CIN III 或 cancer 亦不會知道﹐延誤治療可能有得醫變無得醫！所以不用多想！
