Cancer is a class of diseases through invasion or by implantation into distant sites by metastasis. This unregulated growth is caused by damage to DNA, resulting in mutations to genes that control cell division. Several mutations may be required to transform a normal cell into a malignant cell. These mutations are often caused by chemicals or physical agents called carcinogens. Some mutations occur spontaneously, or they can be inherited as germ line mutations.
Tumor (American English) or tumour (British English) originally means "swelling", and is sometimes still used with that meaning. Tumor meaning swelling is one of the five classical characteristics of inflammation. However, the term is now primarily used to denote abnormal growth of tissue. This growth can be either malignant or benign. It is similar in meaning to a neoplasia.
Malignant tumors are called cancer. Cancer has the potential to invade and destroy neighboring tissues and create metastases. Benign tumors do not invade neighboring tissues and do not seed metastases, but may locally grow to great size. They usually do not return after surgical removal.

A benign tumor sits there and grows slowly. If you remove it, it doesn't return. However, if it is in the wrong place (like deep in the brain), it can still kill.
Cancer is a malignant tumor, which invades tissues aggressively. It may only invade locally, or it may metastasize and spread to areas far away, like the lungs and liver. The most malignant types grow rapidly and have already spread or metastasized to other organs before the original tumor is detected. So a malignant tumor of the skin that is only locally invasive can have a better outlook than a benign tumor of the brain.
Cancers are now "staged", or classified into degrees of malignancy. The mild types have a more hopeful outlook than the severe types.
There are two types of tumors: Benign and Malignant. Malignant tumors are called cancer. They spread rapidly, invading neighbouring cells and often metastasize (release portions of the tumor which will invade other parts of the body). Benign tumors do not invade neighbouring cells but will grow locally.
Cancer is cells multiplying non-stop, as though they were single celled instead of part of a body. One of the things that can cause is a tumor, when the cancer cells are multiplying in once place until it makes a big lump.
But cancer cells can float in the bloodstream or be spread over an organ without making the mass that is a tumor.
A "benign" tumor is one that is not growing rapidly and is not spreading; it is not considered cancer. A malignant tumor is cancer, and it is growing rapidly and/or splitting off cells that will then continue to multiply somewhere else
Cancer is a disease that there is no cure for but there is treatment for. Tumors can be cancerous or non-cancerous. Non-cancerous tumors won't hurt you (you can live with those in your body for years).
Cancer is the result of a tumor.
A tumor is a mass of cells that keep growing and dividing uncontrollably. They do not die like normal cells.
There are two types of tumors - benign and metastatic. Benign tumors are growths that are localized. They just grow and grow and push and compress everything around it. Most cancer caused by benign tumors can be treated by just removing the mass of cells.
Metastatic tumors grow and invade the surrounding tissues and can invade blood and lymph vessels to be carried around the body to invade more organs. These are more dangerous and are harder to kill because the treatment (radiation and chemotherapy) kills healthy cells also.
cancer could be solid tumors or non ..
tumors could be cancer and could be benign tumor .
