Cancer

Asbestos and Benzene are examples of carcinogens known to cause cancer in humans. Argon and Formaldehyde are not classified as carcinogens.

In every cell, the following genes are available.

* The first gene is the cancer gene. If this gene, which is usually dormant, gets activated by being exposed to some radioactive material or by other means, it will cause the cell to multiply over and over again skipping the interphase. Because we have such a gene, we also have a backup. * A second gene is the self-destruct gene. When the entire cell is wrong (which can go from defective organelles to the cell itself) the cell tells all the lysosomes to burst and release their digestive enzymes all over the cell, causing the cell to be digested inside out. What happens with evident cancer is the defect with both genes. the cancer gene is turned on and the self-destruct gene is turned off, allowing that out-of-control cell to freely divide itself.

Cell division is related to the spread of cancer because cancer is uncontrolled cell division. So they are closely related.

Short Answer is: carcinoma is cell-division when the normal program of cell-division has 'been compromised', i. e. altered.

It is related because when the cell divides, sometimes it can cluster up... like a crowded room. then it starts to sort of push away the good cells so there is basically more room to breathe. eventually, this cluster of cells becomes one big ball and starts to spread to other parts of the body and develop more bad clustered cells again only in a different part of the body. This is how cancer forms and spreads to other organs in your body.

Cancer is a disease of cell division. It occurs when abnormal cells grow uncontrollably and invade surrounding tissues. The circulatory system can play a role in cancer by allowing cancer cells to spread to other parts of the body (metastasis) through the bloodstream.

Invasion of cancer cells refers to the ability of cancer cells to penetrate and spread into nearby tissues. Metastasis, on the other hand, involves the spread of cancer cells from the primary tumor to distant organs or tissues in the body through the bloodstream or lymphatic system. Metastasis is a more advanced stage of cancer progression and is often associated with a poorer prognosis.

Non-cancerous cells that do not affect health are referred to as normal cells. These cells function properly within the body and perform their intended roles without causing harm or disrupting the normal functioning of tissues and organs.

There is no evidence to suggest that cancer cannot develop in space. Exposure to space radiation, lack of gravity, and other factors could potentially impact cancer development, but research on this topic is ongoing. Astronauts are monitored closely for cancer and other health issues after returning from space missions.

Abnormal p53 can lead to uncontrolled cell growth because it is unable to properly regulate the cell cycle or initiate cell death (apoptosis) in response to DNA damage or other cellular stressors. This can allow damaged cells to proliferate and accumulate mutations, ultimately leading to the development of cancer.

Marie Curie died of aplastic anaemia, not cancer, likely caused by her long-term exposure to radiation during her research. She passed away in 1934, approximately 29 years after her discovery of radium.

Tumor necrosis factor (TNF) is a cytokine produced to stimulate macrophages and induce cell death in cancer cells. It plays a role in the immune response against cancer by promoting inflammation and cell death in tumor cells.

One could argue that all body cells can potentially become cancerous and therefore they are all dormant cancer cells. But by that definition, a dormant cancer cell is just a normal, healthy cell.

Radium does not cure cancer. However, it has been used in the past for cancer treatment because of its ability to destroy cancer cells. This treatment method is known as radiation therapy, where high-energy radiation is used to kill cancer cells and shrink tumors.

One way to support your body in killing cancer cells is through immunotherapy, which helps the immune system identify and attack cancer cells. Additionally, maintaining a healthy lifestyle with a balanced diet, regular exercise, and stress management can help boost your immune system to fight cancer cells.Consult with a healthcare professional to explore specific treatment options based on your individual circumstances.

The study of cancer is called oncology, while the treatment of cancer is called oncology.

Bladder cancer typically begins when cells in the bladder start to grow abnormally and form a tumor. This cancer can develop due to a combination of genetic factors, exposure to certain environmental toxins such as tobacco smoke, and chronic bladder irritation or inflammation. Early detection and treatment are essential for managing bladder cancer effectively.

Viruses can be engineered to specifically target and infect cancer cells, causing them to die. Some viruses can also stimulate the immune system to recognize and attack cancer cells. Additionally, certain viruses have the ability to directly interfere with the replication process of cancer cells, leading to their death.

A non-cancerous growth of the prostate is called benign prostatic hyperplasia (BPH). This condition leads to an enlargement of the prostate gland and can cause symptoms such as frequent urination, especially at night, and difficulty urinating. While BPH is non-cancerous, it can still cause issues and may require treatment.

Taxol binds to ß-tubulin to promote microtubule assembly and it stabilises the microtubules and messes up the equilibrium between tubulin and microtubule. A cell with stable microtubules proceeds to programmed cell death without dividing.

Disease

It refers to the spreading of a disease-causing agent from one major point of focus to either another specific area or a general dispersal. It usually is used to refer to the spreading of cancer from one area for another. For example, when Breast cancer spreads somewhere else.

Cancer cells can form tumors in other tissues through a process called metastasis, where they break away from the primary tumor, travel through the bloodstream or lymphatic system, and invade other organs or tissues in the body. They can then proliferate and grow in these new locations, forming secondary tumors.

The regular cells that naturally replace themselves get mutated. Those mutated cells keep splitting and replacing dead cells at the normal rate, which is very fast. In a few seconds, 10 million cells die and are replaced. Because of this, cancer cells can spread quickly.

Breast cancer typically develops in stages, starting with normal breast cells mutating into abnormal cells (hyperplasia), then progressing to non-invasive breast cancer (carcinoma in situ), and finally to invasive breast cancer, where the cancer cells invade surrounding breast tissue and can potentially spread to other parts of the body (metastasis).

Small interfering RNA (siRNA) can kill cancer cells by targeting specific genes or pathways that are crucial for cancer cell survival or growth. When siRNA enters the cancer cells, it binds to its complementary mRNA, leading to degradation of the mRNA and inhibition of protein synthesis. This disrupts crucial cellular processes in the cancer cells, ultimately leading to their death.

Yes. I had to have an MRI and they encouraged (borderline forced) me to listen to some music in headphones in order to distract from the noise of the equipment and keep me calm in order to yield a more accurate reading. :)

I knew this was true for an MRI, but is it also true for radiation therapy for advanced stage of cancer?

I'm not sure about that. Sorry. :( It is often ok, but many times therapists may need to speak to you and if you are unable to hear them, you will not be able to follow their instructions.
