what is the difference between grade 1 and stage 1 cancer?

The grading system that's usually used is as follows: grade I – cancer cells that resemble normal cells and aren't growing rapidly. grade II – cancer cells that don't look like normal cells and are growing faster than normal cells. grade III – cancer cells that look abnormal and may grow or spread more aggressively.

Stage I cancer is no more than 2 centimeters in size (about 1 inch) and has not spread to lymph nodes in the area. Stage II cancer is more than 2 centimeters, but less than 4 centimeters (less than 2 inches) and has not spread to lymph nodes in the area.

Stage II non-small cell lung cancer is divided into stages IIA and IIB. In stage IIB, the tumor is 5 centimeters or smaller and cancer has spread to the lymph nodes on the same side of the chest as the primary tumor. The lymph nodes with cancer are in the lung or near the bronchus.

Stage 1 usually means that a cancer is small and contained within the organ it started in. Stage 2 usually means that the tumour is larger than in stage 1 but the cancer hasn't started to spread into the surrounding tissues.

Stage I, Stage IIA and Stage IIB (early) refer to early breast cancer. Stage IIB (advanced), Stage IIIA, Stage IIIB, Stage IIIC and Stage IV refer to advanced breast cancer (locally advanced breast cancer or metastatic breast cancer).

In stage IIA, cancer (1) is found in one-half or less of one side of the prostate. The prostate-specific antigen (PSA) level is at least 10 but lower than 20 and the Grade Group is 1 (Gleason score is 6 or less); or (2) is found in more than one-half of one side of the prostate or in both sides of the prostate.

Grade 2 is the equivalent of in between grades E and F. Grade 1 is the equivalent of in between grades F and G.

stage I – the cancer is small and hasn't spread anywhere else. stage II – the cancer has grown, but hasn't spread. stage III – the cancer is larger and may have spread to the surrounding tissues and/or the lymph nodes (part of the lymphatic system)

Elevated blood pressure tends to get worse over time unless steps are taken to control blood pressure. Stage 1 hypertension. Stage 1 hypertension is a systolic pressure ranging from 130 to 139 mm Hg or a diastolic pressure ranging from 80 to 89 mm Hg.

Higher grade (grade III or IV) tumors tend to grow quickly and are more likely to grow into nearby tissues. These tumors often require more intense treatment.

The earliest stage colorectal cancers are called stage 0 (a very early cancer), and then range from stages I (1) through IV (4). As a rule, the lower the number, the less the cancer has spread. A higher number, such as stage IV, means cancer has spread more. And within a stage, an earlier letter means a lower stage.

The stage of a cancer describes the size of a tumour and how far it has spread from where it originated. The grade describes the appearance of the cancerous cells. If you're diagnosed with cancer, you may have more tests to help determine how far it has progressed.

Grade 1 (low-grade tumor): These cells divide at a low rate and therefore grow slowly. Grade 2 (intermediate-grade tumor): These cells divide at an intermediate rate. Grade 3 (high-grade tumor): These cells divide at a fast rate and therefore grow quickly.

In Stage 1 breast cancer, cancer is evident, but it is contained to only the area where the first abnormal cells began to develop. The breast cancer has been detected in the early stages and can be very effectively treated. Stage 1 can be divided into Stage 1A and Stage 1B.

But, like stage 1, there's no evidence that it has spread to nearby lymph nodes or other organs, so it's also considered N0 and M0. As in stage 1, a stage 2 cancerous kidney will probably be removed, and follow-up therapy might not be necessary.

the main difference between stage 1 and 2 formulas is that the stage 2 contains more iron. by 6 months the iron they got from us has depleted, so they need to get it from their formula instead (unless breastfeeding).

grade 1 – looks most like normal breast cells and is usually slow-growing. grade 2 – looks less like normal cells and is growing faster. grade 3 – looks different to normal breast cells and is usually fast-growing.
