malignant tumor
A tumor is considered cancerous when it consists of abnormal cells that have the potential to invade surrounding tissues or spread to other parts of the body, a process known as metastasis. Cancerous tumors can originate from any type of tissue or organ in the body and are characterized by uncontrolled cell growth. Key features that distinguish cancerous tumors from benign tumors include: Invasiveness: Cancerous tumors can invade nearby tissues and organs. This invasion disrupts the normal structure and function of surrounding tissues. Metastasis: Cancerous cells can break away from the primary tumor and spread to other parts of the body through the bloodstream or lymphatic system. The formation of secondary tumors in distant organs or tissues is a hallmark of cancer. Abnormal Cell Growth: Cancerous tumors consist of cells that exhibit abnormal growth patterns, such as rapid proliferation, loss of normal cellular function, and resistance to signals that regulate cell growth and death. Histological Characteristics: Examination of cancerous tissue under a microscope typically reveals features such as abnormal cell morphology, increased nuclear size, irregular nuclear shape, and increased mitotic activity (cell division). Genetic Alterations: Cancerous cells often harbor genetic mutations or alterations that drive their abnormal growth and behavior. These mutations may affect genes involved in cell cycle regulation, DNA repair, apoptosis (programmed cell death), and cell signaling pathways. It's important to note that not all tumors are cancerous. Benign tumors, for example, do not invade surrounding tissues or spread to other parts of the body. They typically grow slowly and are usually not life-threatening, although they may cause symptoms depending on their size and location. The distinction between cancerous (malignant) and non-cancerous (benign) tumors is crucial for determining appropriate treatment strategies and predicting patient outcomes. Biopsy, imaging studies, and other diagnostic tests are used to evaluate tumors and determine whether they are cancerous or benign.
a cancerous cell is created when DNA or RNA is mutated or damaged in some way during mitosis in which the cell is dramatically changed but still functions. These cells then replicate rapidly and destroy surrounding tissue, & also may spread through the body in blood
A cancerous cell.
Any cell/organ in the human body can become cancerous.
It can give cancer to all the other cells, so it causes more cells to be cancerous. It goes all around the body and the number of the cancer cells will get much more than the first.
Not all but most of them with exception being cancerous cell. Our body fails to detect the cancer cell
It is also spread by germs. But orignally this disease can be spread by the cells throughtout the body.
Most cancerous tumors are detected at advanced phase of the cell cycle.

I Think that the blood cell is in your arm and the nerve cell is in your body what they both have in common is they are in your body. thank you
