According to Dr Ashley Ng of the Walter and Eliza Hall Research Institute's cancer and haematology division, getting cancer from one person to another via blood is exceedingly improbable in healthy persons who are not immune-suppressed.
Cancer cells can be found in the blood of people with cancer but this is very unusual. Getting cancer by way of blood transfusions or organ transplants is possible but very rare events that are not likely to happen to most people.
The only way you could get cancer from someone else's blood is if they have cancer cells circulating in their blood at the time they bleed. These cells would need to find a patient with weak blood vessels so that they could grow into new tumors.
People may wonder if cancer can be transmitted through blood products such as plasma or red blood cells. The FDA has taken measures to try to prevent this form of transmission, for example by testing these products for cancer cells before they are sold. However, despite these efforts, some products will still contain cancer cells because cancers are hard to detect even with modern technology. If you were to receive an infusion of plasma or red blood cells derived from someone who had recently been diagnosed with cancer, you would be given special instructions about how to act if you experience any symptoms related to blood clots (such as pain, swelling, or discoloration of the skin).
No, in general. Cancer is not a contagious illness that spreads quickly from one person to the next. The only time cancer may transfer from one person to another is during organ or tissue donation. In this case, the donor's rights and preferences should be considered when deciding whether to accept or reject an organ or tissue transplant.
Cancer is a complex disease that results from the interaction of genetic factors with environmental triggers. It is not caused by anything you might have been exposed to, such as cigarettes smoke, chemicals, or viruses. However, some cancers are more likely to be passed down through families who live in close proximity or who have similar lifestyles. For example, people who have had multiple friends or family members diagnosed with oral cancer are likely to develop it themselves.
Some types of cancer are associated with specific genes mutations that can be inherited from either parent. These include breast cancer, ovarian cancer, prostate cancer, and colon cancer. Other types of cancer are due to exposures outside the home environment including smoking and exposure to certain chemicals. Still others are due to exposures inside the home including radon gas and asbestos fibers. Finally, some cancers are called "idiopathic" which means no cause can be identified. These include cases where a patient does not have any risk factors but still develops cancer. Idiopathic cancers make up about 20% of all cases.
Even then, the risk is very small.
However, cancer does spread from place to place on the body by means of tiny particles called cells. These cells break down and are taken out of the body in urine, stools, saliva, and sweat. Sometimes cells die and are lost; other times they stick to other cells and form new structures. Either way, they go away when they are broken down or removed by washing with water and soap.
Cancers can also spread because they create special conditions at their site of origin that help them grow and spread faster. For example, if a tumor forms in the bone, it will stimulate new blood vessel formation which will bring nutrients to the tumor and help it grow. If tumors form in the lungs, they will stimulate growth of new nerve fibers that connect with other tumors forming a network across the body. This is why it is important to stop the first tumor before it has a chance to spread.
Cancers can also spread via the blood. Here, cancer cells travel through the blood and find their way into other parts of the body where they grow into more tumors.
Someone in the United States dies from a blood malignancy every 9 minutes. 56,840, or 9.4 percent, of the almost 606,520 persons estimated to die from cancer this year will have been diagnosed with a blood malignancy. Despite the advances achieved in the battle against blood cancer, there is still more work to be done. Everyone can play an important role in preventing blood cancers by using protection against sun exposure, stopping smoking, and testing for blood abnormalities even if they are not symptoms of disease.
Cancer of the blood means cancer that has started in the blood cells, plasma, or bone marrow. It is also called hemoblastosis or hodgkin's disease. The three most common types of cancer of the blood are chronic myeloid leukemia (CML), acute lymphoblastic leukemia (ALL), and polycythemia vera (PV). Other forms of cancer that may develop into blood diseases include multiple myeloma, non-Hodgkin's lymphoma, and Waldenström's macroglobulinemia. People with these disorders may experience serious complications due to decreased blood cell counts, increased red blood cell destruction, and accumulation of abnormal proteins in blood (abnormal immunoglobulins).
Cancers that start in the blood cells usually affect both males and females about equally. Cancer of the blood affects people of all ages but is most common among young adults between 20 and 40 years old.
Blood cancers are very serious diseases and without treatment many people would already be dead.
Blood cancers are classified according to the type of immune cell that is producing too many cells or not functioning properly. These classes include B-cell lymphomas, multiple myeloma, and leukemia. Each type of cancer has various subtypes that are defined by the type of immune cell that is producing them. For example, there are several types of B-cell lymphoma including diffuse large B-cell lymphoma (DLBCL), follicular lymphoma (FL), chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL), and marginal zone lymphoma (MZL).
The term "blood cancer" may cause someone who is afraid of losing a loved one to think that it is a fatal disease. However, despite its name, blood cancer doesn't necessarily mean that it spreads to other parts of the body through the blood. Spreading cancer to other parts of the body via microscopic deposits called tumors emboli can occur in patients with blood cancers such as acute myeloid leukemia (AML) and acute lymphoblastic leukemia (ALL).
