2. Papillary Carcinoma
Papillary carcinoma is a differentiated form of thyroid cancer (DTC), also sometimes referred to as well-differentiated (WDTC). It is the most common kind of thyroid cancer. The name well-differentiated comes from the fact that these cancerous cells still resemble healthy cells, but originate from the follicular cells of the thyroid, says Thyroid Cancer Canada. It accounts for over half of the cases (about 60-percent, according to NHS), and typically affects women under the age of 40.
WebMD describes it as growing slowly, but that it will eventually spread to the nymph nodes in the neck. The source also says that most people who are diagnosed with this type of thyroid cancer have a good chance at a full recovery.
