Stage 1 non-small cell lung cancer Stage 1A: The cancer affects the lung only, with a tumor that measures 3 cm or smaller and hasn't spread to lymph nodes or other areas. Stage 1B: In some cases, the lung tumor is larger than 3 cm, but smaller than 4 cm, and hasn't metastasized to lymph nodes.
Stage 1A2 means: the cancer is between 1cm and 2cm. It has not grown into the membranes that surround the lungs (pleura) it has not grown into the main branches of the airways.
Stage IA tumors are 3 centimeters (cm) or less in size. Stage IA tumors may be further divided into IA1, IA2, or IA3 based on the size of the tumor. Stage IB tumors are more than 3 cm but 4 cm or less in size.
In stage 2 breast cancer, the tumor measures between 2 cm and 5 cm, or the cancer has spread to the lymph nodes under the arm on the same side as the breast cancer.
Stage I (“stage 1”): Cancer is in your lung tissues but not your lymph nodes. Stage II (“stage 2”): The disease may have spread to your lymph nodes near your lungs. Stage III (“stage 3”): It has spread further into your lymph nodes and the middle of your chest.
Stage 2 lung cancer is still considered early lung cancer, but it's usually locally advanced.
Stage II (2) lung cancer is considered an early-stage form of the lung disease and may be curable through surgery or a combination of treatments like chemotherapy and radiation.
2 cm is about the size of a peanut. 3 cm is about the size of a grape. 4 cm is about the size of a walnut. 5 cm is about the size of a lime.
Primary breast tumors vary in shape and size. The smallest lesion that can be felt by hand is typically 1.5 to 2 centimeters (about 1/2 to 3/4 inch) in diameter. Sometimes tumors that are 5 centimeters (about 2 inches) — or even larger — can be found in the breast.
Stage 1 non-small cell lung cancer
Stage 1A: The cancer affects the lung only, with a tumor that measures 3 cm or smaller and hasn't spread to lymph nodes or other areas. Stage 1B: In some cases, the lung tumor is larger than 3 cm, but smaller than 4 cm, and hasn't metastasized to lymph nodes.
What is stage 1 lung cancer? Stage 1 lung cancer is considered early-lung cancer, meaning that the tumor is relatively small and hasn't spread to lymph nodes or any other part of the body, so the N and M are not factors. Most stage 1 lung cancers are non-small cell lung cancer (NSCLC).
The most common areas for lung cancer to spread to are: nearby lymph nodes or a single distant lymph node. the brain. bones.
In contrast, Mydral et al16 found the time from onset of symptoms to treatment was shorter in patients with stage IV lung cancer (median 3.4 months) than in those with stage I/II disease (median 5.5 months).
Early stages of non-small lung cancer (stages 0 and 1) have a better prognosis than later stages (stages 2, 3 or 4). With small cell lung cancer, limited stage cancers have a better prognosis than extensive stage cancers.
Studies have shown that lung cancer doubling time can vary, from 229 days to 647 days in one study, depending upon the type. 7 It's possible that some types of lung cancer progress within weeks to months, while others may take years to grow.
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.
Size of the tumour
Tumour size will affect prognosis no matter how many lymph nodes have cancer in them.
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. Sometimes stage 2 means that cancer cells have spread into lymph nodes close to the tumour. This depends on the particular type of cancer. Stage 3 usually means the cancer is larger.
Stage 1A means that the cancer is 2 centimetres (cm) or smaller and has not spread outside the breast.
Scientists have found that for most breast and bowel cancers, the tumours begin to grow around ten years before they're detected. And for prostate cancer, tumours can be many decades old. “They've estimated that one tumour was 40 years old. Sometimes the growth can be really slow,” says Graham.
One of the largest tumors ever taken out of a human was a 303-pound ovarian tumor removed at Stanford Hospital in 1991, according to a 1994 report. In the newly reported case, physicians removed the 132-pound tumor as well as 6 pounds of abdominal wall tissue and excess skin that had been stretched by the tumor.
Chemotherapy. Chemotherapy may be offered after surgery for stage 2 non–small cell lung cancer if you are healthy enough to have chemotherapy. Research has shown it might improve survival in some people with early stage lung cancer. Your healthcare team will discuss the benefits and risks of chemotherapy with you.
For brain or lung metastasis, the larger the tumor, the higher the risk of brain or lung metastasis.
Stage I is also called early-stage lung cancer. It often can be cured, and most people can expect to live 5 years or longer.
