T1a1 is measured stromal invasion 3
T1a is defined as tumor that invades the lamina propria
T1a melanoma
T1b1 is clinically visible lesion 4
T1b is clinically visible lesion confined to the cervix or microscopic lesion greater than T1a (B and C)
T1 for adenosarcoma is tumor limited to the uterus
T1 for the supraglottis is defined as tumor limited to one subsite of supraglottis (shown here in the epiglottis) with normal vocal cord mobility
T1 is defined as a tumor 2 cm or smaller in greatest dimension
T1 is defined as tumor 2 cm or less in greatest dimension limited to the thyroid
T1 is defined as tumor with a maximum clinical diameter 2 cm
T1 is tumor confined to vagina
T1 tumor of the hypopharynx with involvement of the post-cricoid area
T1 tumor of the hypopharynx with involvement of the pyriform sinus

T2a2 is clinically visible lesion more than 4
T2a melanoma
T2b: Tumor larger than 10 cm in greatest dimension
T2b is tumor with parametrial invasion
T2 for leiomyosarcoma, endometrial stromal sarcoma, and adenosarcoma is tumor extending beyond the uterus, within the pelvis
T2 for the supraglottis with invasion of ventricular bands (false cords) and the epiglottis
T2 involves each of the ipsilateral pleural surfaces (parietal, mediastinal, diaphragmatic, and visceral pleura) with at least one of the following: involvement of diaphragmatic muscle (as illustrated) and/or extension of tumor from the visceral pleura into the underlying pulmonary parenchyma (as illustrated)
T2 is defined as tumor 5 cm, no extra-adrenal invasion
T2 is defined as tumor more than 2 cm but not more than 4 cm in greatest dimension limited to the thyroid
T2 is defined as tumor with a maximum clinical diameter 2 but 5 cm
T2 is tumor invading paravaginal tissues but not to pelvic wall
T2 tumor of the hypopharynx with involvement of the posterior wall of the hypopharynx
T2 tumor of the hypopharynx with involvement of the pyriform sinus and the post-cricoid area
