The tumor measures between 2 and 5 cm and small groups of cells (between 0.2 and 2 mm) exist in the axillary lymph nodes. The pathology report says there was a 2.5 cm mass, RCC mostly grade 1 but the presence of some more defined nuclei raises it to grade 2 (I think the surgeon was surprized and was expecting grade 1), primary tumor is identified as: pT1a pNX. The diagnosis of cancer is confirmed. Stage 4. Stages 1, 2, and 3. A total of 149,912 patients met study criteria and were included in the study. The numbers represent how large the primary tumor has grown and how far the cancer has spread. not sure but close enough. Either a single tumor larger than 2 cm (4/5 inch) that has grown into blood vessels, OR more than one tumor but none larger than 5 cm (about 2 inches) across (T2). Size doesn’t tell the whole story, though. Size is used to help determine the stage of the breast cancer. OR; The tumor measures larger than 5 cm but isn't in the axillary lymph nodes. OR; The tumor measures 2 to 5 cm and there is cancer in up to three axillary lymph nodes. IIIA T3. T1: The tumor is 2 cm or smaller and has grown past the top layer of cells and into the layers beneath, such as the lamina propria or submucosa. The databases were not combined at any point for the analysis. A 1.3 centimeter tumor is 1.3 centimeters, which can also be called 13 millimeters. That risk increases significantly if the polyp is greater than 10 mm (1 cm); research has shown the larger a colon polyp becomes, the more rapidly it grows. It has not spread to nearby lymph nodes (N0) or to distant sites (M0). T0 (T plus zero): There is no evidence of a tumor. All of the cancer… Doctors measure cancer in millimeters (1 mm = .04 inch) or centimeters (1 cm = .4 inch). A centimeter is measured using the metric system, as opposed to the imperial or U.S. system of measurement. The tumor was T2, had gone into the muscle but not through the muscle wall. Patients with total tumor … Patients with cancers smaller than 2 cm were analyzed, and they were divided into two groups based on tumor size: T1a ( < 1 cm) and T1b ( 1-2 cm). Of these, 65% had T1a tumors and 35% had T1b tumors. The size of a polyp typically does make a difference. The larger the polyp becomes, the bigger the risk of it developing into colon cancer. In the study, published online in the British Journal of Cancer, the average total tumor dimension was 7.5 centimeters, or roughly 3 inches. T1b: The tumor is between 1 cm and 2 cm in size. M0. This is a little over half an inch. I believe my tumor was 1.7 to 1.8 cm. There are other risk factors that go along with tumor size for staging, so a small tumor may or may not be less advanced than a large tumor with other risk factors. Tumor Size In Millimeters: Description: Drawing shows different sizes of common items in millimeters (mm): a sharp pencil point (1 mm), a new crayon point (2 mm), a pencil-top eraser (5 mm), a pea (10 mm), a peanut (20 mm), and a lime (50 mm). A T-1 tumor is up to 2 cm, a T-2 is 2-4cm, and T-3 is above 5 cm. As someone else said on this thread, tumor size does not necessarily mean it hasn't spread to lymph nodes. Also shown is a 2-centimeter (cm) ruler that shows 10 mm is equal to 1 cm. 2 cm is on the small size. N0. A ruler, the most common device used to measure distances, uses calibrated lines denominated into centimeters or inches, making it easy to compare between the two systems. T1a: The tumor is less than 1 cm in size. Size indicates how large across the tumor is at its widest point. More than one tumor, with at least one tumor larger than 5 cm …
