Just like regular cells, cancer cells also need nourishment to grow. This nourishment is available though blood supply. Since cancer cells grow as an irregular mass, most often, there is no blood supply to certain regions of the cancer cell mass (also known as a tumor)
Therefore, these tumors redirect the growth of blood vessels to help them get blood supply

Does amino acid kill cancer cells?
No. Amino acids are the building blocks of proteins. They're not cytotoxic, which is what they'd need to be to kill cancer cells.
Why do organisms need new cells?
Because cells become and they don't function properly.
What cells primarily target cancer cells?
Cells of the immune system, particularly certain types of white blood cells, primarily target cancer cells. The main types of immune cells involved in targeting cancer cells include: Cytotoxic T Cells (CD8+ T Cells): These cells directly attack and destroy cancer cells by recognizing specific antigens present on the surface of the cancer cells. Natural Killer (NK) Cells: NK cells are a type of lymphocyte that can recognize and kill abnormal cells, including cancer cells, without prior sensitization or the need for specific antigens. Macrophages: Macrophages are immune cells that engulf and digest foreign substances, including cancer cells, through a process called phagocytosis. They also play a role in presenting antigens to other immune cells to initiate an immune response against cancer. Dendritic Cells: Dendritic cells are antigen-presenting cells that capture antigens from cancer cells and present them to T cells, thereby activating an adaptive immune response against the cancer. Tumor-Infiltrating Lymphocytes (TILs): These are lymphocytes that have migrated into the tumor microenvironment and are involved in recognizing and attacking cancer cells. Cytokine-Induced Killer (CIK) Cells: CIK cells are a type of immune cell that has been activated and expanded outside the body and then reintroduced into the patient to target and kill cancer cells. These immune cells, along with other components of the immune system, form a complex network known as the immune response, which plays a crucial role in recognizing and eliminating cancer cells from the body.
In what ways do cancer cells differ from other cells?
Cancer cells differ from normal cells in several key ways: Uncontrolled Growth: Cancer cells grow and divide uncontrollably, forming tumors. Normal cells, on the other hand, undergo regulated growth and division, only dividing when necessary for tissue repair or replacement. Lack of Apoptosis: Cancer cells evade apoptosis, the programmed cell death that occurs in normal cells to remove damaged or unnecessary cells. This allows cancer cells to survive and accumulate, contributing to tumor growth. Insensitivity to Signals: Cancer cells may ignore signals from neighboring cells or the body's immune system that would normally regulate cell growth and division. This insensitivity allows cancer cells to proliferate unchecked. Angiogenesis: Cancer cells stimulate the formation of new blood vessels (angiogenesis) to supply nutrients and oxygen to the growing tumor. Normal cells do not typically induce angiogenesis in the absence of injury or physiological need. Metastasis: Cancer cells have the ability to invade nearby tissues and spread to distant organs through the bloodstream or lymphatic system, a process known as metastasis. Normal cells remain localized and do not spread throughout the body in the same way. Genomic Instability: Cancer cells often have genetic mutations or chromosomal abnormalities that result in genomic instability. This genetic instability contributes to tumor heterogeneity and can drive cancer progression and treatment resistance. Altered Metabolism: Cancer cells exhibit altered metabolism, favoring glycolysis (the breakdown of glucose) even in the presence of oxygen, a phenomenon known as the Warburg effect. This metabolic shift provides cancer cells with the energy and building blocks needed for rapid proliferation. Immune Evasion: Cancer cells may evade detection and destruction by the immune system through various mechanisms, such as downregulating immune recognition molecules or secreting immunosuppressive factors. This immune evasion allows cancer cells to survive and proliferate in the body. Overall, cancer cells exhibit multiple hallmarks of malignancy that distinguish them from normal cells, reflecting their dysregulated behavior and aberrant biology. Understanding these differences is crucial for developing effective strategies for cancer prevention, diagnosis, and treatment.
What do you need stem cells for?
Stem cells are needed because they become specialized cells within the body, helping organs regenerate and heal.
How many cancer cells do you need to get cancer?
you actually just get cancer if you have to many cells in a particular place and its when you have double the amount your supposed to have you get cancer
What precautions need to be taken when using chemotherapy to treat cancer?
Chemotherapy usually causes destruction of normal cells, and cancer cells can become immune to chemical destruction. Side effects and patient tolerance issues typically are anticipated and dosages may have to be.
Does amino acid kill cancer cells?
No. Amino acids are the building blocks of proteins. They're not cytotoxic, which is what they'd need to be to kill cancer cells.
Explain why cancer cells need a greater blood supply than normal cells?
the cancer cells need to grow very rapidly for which they need a lot of blood. (i think) they can form new blood vessels anywhere in the body to ensure that they get blood, this is known as angiogenesis.
Why do many cancers harm the body?
Cancer is a cell mutation where the cell reproduces rapidly and too much. Then those new cells become cancer cells and continue to split out of control. Yet, the body does not need so many of one type of cell so quickly. The cancer cells are large in quantity and take over that area, causing pressure on other normal healthy cells. Those tissues are overthrown by the cancer ones and it off-sets the balance of the body. This is dangerous because you need a specific amount of everything in your body to work, so you have many cancer cells and less of the healthy cells and can be very hazardous to countless of daily functions necessary to life. There really is only one Cancer, and that's just cancer, no matter where it is in your body. It just affects different cells. i.e.- Lung cancer is a mutation in lung cells, and Brain cancer is a mutation in brain cells. The only two categories cancer is divided into generally are malignant and benign. Malignant cancer will carry the cancerous cells by the bloodstream to other parts of the body, and the cancer will then affect that spot as well. This cancer is slightly more dangerous than benign cancer, which will only stay in the organ where it first started and will not travel through the body.
What is atypical cells?
Atypical cells are cells that appear to be abnormal and need further testing to determine why they are abnormal. Sometimes these cells can end up being cancer but not all atypical cells will.
Why do you need to drink 8 glasses of water a day?
to drown cancer cells
Why do organisms need new cells?
Because cells become and they don't function properly.
How do you get a tumor?
Cancer is a term used for diseases in which abnormal cells divide without control and are able to invade other tissues. Cancer cells can spread to other parts of the body through the blood and lymph systems.Cancer is not just one disease but many diseases. There are more than 100 different types of cancer. Most cancers are named for the organ or type of cell in which they start -- for example, cancer that begins in the colon is called colon cancer; cancer that begins in basal cells of the skin is called basal cell carcinoma.Cancer types can be grouped into broader categories. The main categories of cancer include:-- cancer that begins in the skin or in tissues that line or cover internal organs.Sarcoma -- cancer that begins in bone, cartilage, fat, muscle, blood vessels, or other connective or supportive tissue.Leukemia -- cancer that starts in blood-forming tissue such as the bone marrow and causes large numbers of abnormal blood cells to be produced and enter the blood.Lymphoma and myeloma -- cancers that begin in the cells of the immune system.Central nervous system cancers -- cancers that begin in the tissues of the brain and spinal cord.Origins of cancerAll cancers begin in cells, the body's basic unit of life. To understand cancer, it's helpful to know what happens when normal cells become cancer cells. The body is made up of many types of cells. These cells grow and divide in a controlled way to produce more cells as they are needed to keep the body healthy. When cells become old or damaged, they die and are replaced with new cells.However, sometimes this orderly process goes wrong. The genetic material (DNA) of a cell can become damaged or changed, producing mutations that affect normal cell growth and division. When this happens, cells do not die when they should and new cells form when the body does not need them. The extra cells may form a mass of tissue called a tumor.

Why can cancer have such a serious effect on humans?
My understanding is that cancer actually damages the human cell: According to Dr. Otto Heinrich Warburg(Nobel Prize Winner 1931), the cells change from being 'Aerobic'( oxygen fueled ) to become 'Anaerobic'( sugar Fueled )! As oxygen can no longer be absorbed through the cell, our organs begin to break down and the cancer cells need for sugars, robs our bodies of their nutrients.
What are characteristic of cancer cells?
According to Dr. Otto Heinrich Warburg(Nobel Prize Winner 1931), cancer cells change from being 'Aerobic'( oxygen-fueled ) to become 'Anaerobic'( non oxygen-fueled ), actually sugar-fueled! As oxygen can no longer be absorbed through these cells, our organs begin to break down and the cancer cell's need for sugars, robs our bodies of their nutrients. As oxygen can no longer be tolerated & becomes a poison to the cancerous cells, in their drive to survive they enter into the blood stream and travel to other areas of the body & multiply utilising the old addage of safety in numbers.
