What does the T mean in cancer staging?
A system to describe the amount and spread of cancer in a patient’s body, using TNM. T describes the size of the tumor and any spread of cancer into nearby tissue; N describes spread of cancer to nearby lymph nodes; and M describes metastasis (spread of cancer to other parts of the body).
What is a T1 cancer?
T1: The tumor has grown into the submucosa, which is the layer of tissue underneath the mucosa or lining of the colon. T2: The tumor has grown into the muscularis propria, a deeper, thick layer of muscle that contracts to force along the contents of the intestines.
What is T1 and T2 in breast cancer?
T1 (includes T1a, T1b, and T1c): Tumor is 2 cm (3/4 of an inch) or less across. T2: Tumor is more than 2 cm but not more than 5 cm (2 inches) across. T3: Tumor is more than 5 cm across. T4 (includes T4a, T4b, T4c, and T4d): Tumor of any size growing into the chest wall or skin.
What stage is T3 breast cancer?
T3 means the tumour is bigger than 5 centimetres across. T4 is divided into 4 groups: T4a means the tumour has spread into the chest wall (the structures surrounding and protecting the lungs) T4b means the tumour has spread into the skin and the breast might be swollen.
How do you know if cancer has spread to lymph nodes?
If cancer cells have spread to your lymph nodes (or beyond your lymph nodes to another part of the body), symptoms may include:
- lump or swelling in your neck, under your arm, or in your groin.
- swelling in your stomach (if the cancer spreads to your liver)
- shortness of breath (if the cancer spreads to the lungs)
- pain.
Which notation means there are no known distant metastases?
Metastasis (M category) M0 means that no distant cancer spread has been found.
What is a T3 cancer?
T3 means the tumour has grown into the outer lining of the bowel wall but has not grown through it. T4 is split into 2 stages, T4a and T4b: T4a means the tumour has grown through the outer lining of the bowel wall and has spread into the tissue layer (peritoneum) covering the organs in the tummy (abdomen)
Is a 5cm tumor large?

Is a 2 cm breast tumor large?
it will likely be classified as stage IA. In general, stage IIB describes invasive breast cancer in which: the tumor is larger than 2 cm but no larger than 5 centimeters; small groups of breast cancer cells — larger than 0.2 mm but not larger than 2 mm — are found in the lymph nodes or.
Is a 5mm breast mass big?
In T1a breast cancer, the tumor size is less than or equal to 5 millimeters (mm); in T1b, the tumor size is greater than 5 mm, but less than or equal to 10 mm. T1a and T1b breast cancers without lymph node spread have excellent long-term outcomes, with more than 95% of women alive at 10 years.
What is the survival rate for grade 3 breast cancer?
The relative 5-year survival rate for stage 3 breast cancer is 86 percent, according to the American Cancer Society . This means that out of 100 people with stage 3 breast cancer, 86 will survive for 5 years. But this figure doesn’t consider breast cancer characteristics, like grade or subtype.
