Encapsulated papillary carcinoma of the breast

Encapsulated papillary carcinoma is a non-invasive type of breast cancer. “Non-invasive” means that the cancerous cells are confined to where they started and have not spread to nearby breast tissue. This type of tumour behaves similarly to another non-invasive breast cancer called ductal carcinoma in situ (DCIS), which also has a low risk of spreading. …

Serous tubal intraepithelial carcinoma (STIC)

What is serous tubal intraepithelial carcinoma (STIC)? Serous tubal intraepithelial carcinoma (STIC) is a non-invasive type of fallopian tube cancer. It develops from the cells that cover the inside surface of the fallopian tube. If left untreated, STIC can turn into an invasive type of cancer called high-grade serous carcinoma. Why is serous tubular intraepithelial …

Differentiated vulvar intraepithelial neoplasia (dVIN)

What is differentiated vulvar intraepithelial neoplasia (dVIN)? Differentiated vulvar intraepithelial neoplasia (dVIN) is a pre-cancerous disease that develops on the vulva. It is called a pre-cancerous disease because over time it can turn into a type of vulvar cancer called squamous cell carcinoma. What causes differentiated vulvar intraepithelial neoplasia?
