Usually, all the changes are normal; however metaplasia increases the risk of cervical cancer making the transformation zone, the most common area for cervical cancer to occur. There are two main types of cervical cancer: squamous cell carcinoma and adenocarcinoma. Squamous cell carcinoma which accounts for 90% of cases, starts at the lining of the cervix and develops into pre-cancerous changes which involve mild abnormalities of the squamous cells, leading to cancer.
