Tumor Size In some cases, a tumor may be too large to safely remove through surgery. In others, surgery cannot be done because the tumor is in an essential organ like the liver or pancreas and removing the cancer would mean taking too much of the organ it has invaded along with it.
Blood supply and cancer
As the tumour gets bigger, its centre gets further and further away from the blood vessels in the area where it is growing. So the centre of the tumour gets less and less oxygen and nutrients.
Although many tumors, such as lung, kidney, or breast cancer, do form masses that can be treated surgically, some cannot. This may be because the tumor is in a sensitive location such as the spinal cord, where surgical removal could critically damage surrounding tissue.
Removing a tumor is a common type of cancer surgery. This may also be called a "resection" or "excision." Your doctor usually takes out the tumor and some of the healthy tissue near it. The tissue around the tumor is called the margin. Tumor removal generally requires a larger incision, or cut, than a biopsy.
T1a tumors are over 1 mm and no more than 5 mm in diameter. T1b tumors are over 5 mm and no more than 10 mm in diameter. T1c tumors are greater than 10 millimeters and no more than 20 millimeters. The tumor is larger than 20 millimeters (2 centimeters) and no more than 50 millimeters (5 centimeters).
T1 means the cancer is smaller than 5cm. T2 means the cancer is larger than 5cm, but no larger than 10cm. T3 means the cancer is larger than 10cm, but no larger than 15cm. T4 means the cancer is larger than 15cm.
Glioblastoma often grows into the healthy brain tissue, so it might not be possible to remove all of the cancer cells. Most people have other treatments after surgery to get to the cancer cells that are left.

According to the Guinness World Records, the largest tumorever removed intact weighed 302 pounds. It was removed in 1991 and the woman patient made a full recovery.
Tumors can be classified as benign or malignant. Benign tumors are those that stay in their primary location without invading other sites of the body. They do not spread to local structures or to distant parts of the body. Benign tumors tend to grow slowly and have distinct borders.
A benign tumor is not malignant. It grows more slowly, has even borders and doesn't spread to other parts of your body. Many benign tumors don't require treatment.
stage 3 – the cancer is larger and may have spread to the surrounding tissues and/or the lymph nodes (or "glands", part of the immune system) stage 4 – the cancer has spread from where it started to at least 1 other body organ, also known as "secondary" or "metastatic" cancer.
A tumor is a mass or group of abnormal cells that form in the body. If you have a tumor, it isn't necessarily cancer. Many tumors are benign (not cancerous). Tumors can form throughout the body.
A non-cancerous (benign) soft tissue tumour is a growth that does not spread (metastasize) to other parts of the body. Non-cancerous tumours are not usually life-threatening. They are typically removed with surgery and do not usually come back (recur). There are many types of non-cancerous soft tissue tumours.
Inoperable lung cancer is a tumor that surgery can't treat. This might be because the cancer is in a hard-to-reach spot or for other reasons, like if it's spread outside your lungs. It's also called unresectable lung cancer. Just because you can't have surgery doesn't mean you can't do anything about the cancer.
When your doctor talks to you about treatment for pancreatic cancer, they may tell you that your condition is "inoperable." That means surgery isn't an option for you, usually because the tumor is too large to remove or your cancer has already spread to other parts of your body.

Lung & Bronchus
Lung and bronchial cancer causes more deaths in the U.S. than any other type of cancer in both men and women. Although survival rates have increased over the years due to improved treatments, the outlook is still bleak. The five-year survival rate is only 22%.
Lung cancer is the most aggressive form of cancer. Smoking and tobacco use are the major causes of it. Low-dose CT scans, which can detect cancer earlier, have improved survival rates for those with lung cancer, even among heavy smokers.
While there are well over 100 different types of brain tumors, glioblastoma is typically recognized as the most aggressive primary brain cancer in adults.
Stage IV. This stage means that the cancer has spread to other organs or parts of the body. It may be also called advanced or metastatic cancer.
Stage 4 cancer has spread from its original location to distant parts of the body. It's sometimes referred to as metastatic cancer. This stage may be diagnosed years after the initial cancer diagnosis and/or after the primary cancer has been treated or removed.
Stage IV: The cancer has spread to other organs or areas of your body. This stage is also referred to as metastatic or advanced cancer.
