They are caused by malignant cells. In this case, a tumor would be an abnormal cell mass which develops when controls of the cell cycle and cell division malfunction. These malignant cells accumulate, and they invade their surroundings. These cells can spread via blood by breaking off "the pack". This is why it is important to check for any abnormal growth of lumps or moles, because if you are diagnosed with cancer, it can spread to other parts of the body.
A tumor is an abnormal growth on the body.This happens when cells start reproducing at a higher rate. This is usually the case in cancer.
Tumors form when cells in the body begin dividing out of control. Gradually, a mass begins to take shape, and if it is not removed, a person will become very sick and eventually die.
Neoplasia
Oncogenic means pertaining to oncogenesis, or formation of a tumor.
The inhibition of formation of blood vessels feeding the tumor and contributing to tumor growth.
The process of an egg formation is called ogenesis.
Cementing is not a process involved in the formation of sedimentary rock.
The process of meiosis never results in the formation of a Diploid.
The S-process.
Metastasis
the process through which the tumor supports its growth by creating its own blood supply is called angiogenesis
Chemical prosses, or enzymstic process, is synonymous to bio processes
The formation of a tumor, which may or may not be cancerous.
The process is known as Pedogenesis. Erosion and siltation are two of the mechanisms that contribute to pedogenesis.
