Cancer

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

The production and use of chlorofluorocarbons (CFCs) have been linked to an increase in the occurrence of skin cancers caused by holes in the ozone layer. CFCs were commonly used in aerosol sprays, refrigeration, and air conditioning systems before being phased out due to their harmful effects on the ozone layer. The depletion of the ozone layer allows more ultraviolet (UV) radiation to reach the Earth's surface, leading to an increased risk of skin cancers such as melanoma.

cancer is defined as the numerous growth of harmful cells.so they kill the remaining healthy protecting cells,in this way they kill most of them.they even stop the reproduction of new cells and kill them if they reproduce.

Cancer is difficult to study because it is a complex disease with many different types and causes. Additionally, cancer is highly heterogenous, meaning it can vary greatly from person to person. Understanding the underlying mechanisms of cancer requires interdisciplinary research and advanced technology.

Gold isotopes have various uses such as in medical imaging for cancer treatment, in archaeological dating to determine the age of artifacts, and in nuclear medicine for diagnostic imaging. Additionally, they are used in scientific research for tracing chemical reactions and biological processes.

Cancerous cell growth is called cancer. It occurs when abnormal cells divide uncontrollably and can spread to other parts of the body. Treatment options for cancer may include surgery, chemotherapy, radiation therapy, or targeted therapy.

Cancer results from mutations in the DNA of cells that disrupt normal cellular control mechanisms. These mutations can be caused by factors such as exposure to carcinogens, genetic predisposition, or random errors during cell division. Over time, accumulation of these mutations leads to uncontrolled cell growth and the development of cancer.

A malignant tumor is a mass of cells that grow uncontrollably, invade surrounding tissues, and can spread to other parts of the body, causing harm and potential damage to organs and bodily functions. Treatment often involves a combination of surgery, chemotherapy, and radiation therapy.

Cord blood transplant has three phases. Before the transplant, a person undergoes a series of evaluations, preparative procedures and be kept inside a room with filtration system. Just think the person's immune system is restarted before infusing new blood cells inside your system. The recovery period is a period of high-risks complications but a person is expected to get better after a year or so. Successful stories of cord blood transplant can be read at the blog attached.

Radiation can harm both normal and cancerous cells, but because cancerous cells are often more sensitive to radiation, they may be more likely to be damaged or killed by radiation therapy. Normal cells can repair themselves more effectively than cancerous cells, which helps protect them from the effects of radiation.

Yes, cancer can result from a failure of the cell cycle control system. When the cell cycle control mechanisms that regulate the orderly progression of cell division are disrupted, it can lead to uncontrolled cell growth and division, which are characteristic features of cancer.

Some chemotherapeutic drugs combat cancer by interfering with the ability of cancer cells to grow and divide. These drugs target specific pathways or processes that are vital for the survival of cancer cells, ultimately leading to cell death. Some examples of chemotherapeutic drugs include taxanes, platinum agents, and antimetabolites.

The pH of water alone doesn't directly affect cancer cell growth. However, maintaining a healthy pH balance in the body through proper nutrition and hydration is important for overall health and may indirectly impact cancer cell growth. Consult with a healthcare professional for personalized advice.

The dioxins are a family of ring-based organic chemical compounds with 2 oxygen atoms in place of a couple of the 6 carbon atoms that one normally expect to find in a phenyl ring. Because they are quite chemically active, dioxins tend to be toxic and carcenogenic. Dioxins may be formed as a byproduct of the manufacture of other chemicals (herbicides, for example) or in chemical processes that use chlorine (such as the bleaching process in paper manufacturing). They are also formed as a result of incomplete combustion of chemical compounds (for example, burning plastics in a faulty incinerator). The most notoriously poisonous and cancer-causing dioxin compound known is called TCDD, which is chemistry shorthand for 2,3,7,8-tetrachlorodibenzo-para-dioxin. The most notorious dioxin poisoning event occurred during the Vietnam War, when the US military sprayed tens of millions of gallons of dioxin-containing chemicals such as "Agent Orange". This eventually resulted in nearly a million deaths, disabilities and birth defects in affected individuals, both Vietnamese and Americans.

Yes. You probably have a hernia. A hernia is when one of the tubes that your testicles come through when you are a baby doesn't close completely, and later in life your intestine wiggles into it. You should visit your doctor, and you will probably get surgery.

Cells exhibit an effect known as the Hayflick limit, which states that all cells can divide and reproduce only a limited amount of times. There are a few exceptions to that rule, as some cells known as immortal cells display no signs of aging and can be terminated only by outside factors, such as starvation or if their host dies.

Human germ cells (ovum and sperm) have no Hayflick limit. Many species of bacteria are considered immortal as they continue dividing until an outside force terminates them. Similarly, diseases of the cell cycle (such as cancer) are able to produce immortal cells as they grow and reproduce without limitations.

Anitbiotics helps fight diseases by killing bacteria. Always remember these 3 rules:

Antibiotics=bacteria

Antiviral=virus

Antifungal=fungus

A certain type of medication can only be used for the disease it matches up with (antiviral will not kill a bacteria of fungus infection, only a virus)

Cancer leads to a cell mass called a tumor. Tumors are abnormal growths of cells that can develop in different parts of the body. Tumors can be classified into two main types: benign and malignant.

Benign Tumors: Benign tumors are non-cancerous growths that do not invade nearby tissues or spread to other parts of the body. They usually grow slowly and have well-defined boundaries. Although they are not cancerous, some benign tumors can still cause health problems depending on their size and location.

Malignant Tumors: Malignant tumors are cancerous growths that have the potential to invade nearby tissues and spread to other parts of the body through a process called metastasis. Cancer cells within malignant tumors can break away from the original tumor site and travel through the bloodstream or lymphatic system to form new tumors in distant organs or tissues.

It's important to note that not all tumors are cancerous. Some tumors, like benign tumors, are not life-threatening, whereas malignant tumors, or cancers, can be aggressive and require prompt medical attention and treatment. Early detection and proper management of cancer are crucial for improving treatment outcomes and patient survival rates.

Breast cancer rates have shown variations over time due to factors such as increased screening leading to higher detection rates, changes in lifestyle habits, and advancements in treatment options. It is important to continue promoting awareness, early detection, and access to quality healthcare to further understand and address these changes in breast cancer rates.

Cancer can disrupt the normal regulation of the cell cycle, leading to uncontrolled cell division and tumor formation. Mutations in genes that control cell cycle checkpoints can allow cancer cells to bypass mechanisms that normally prevent excessive cell growth. This disruption of the cell cycle can contribute to the unchecked proliferation of cancer cells.

onocogenes.

Process:

-PO (proto-oncogenes) are moved (closer to promoter/enhancer)

-More PO is made

-Proteins are made in excess (in more excess if it's been in excess from

previous step)

-Mutations at pts

-At PO, causing increase expression

-At coding gene, causing gene protein to resist degeneration

Not really. Ozone holes are a natural repeating phenomenon at each pole. Usually the holes heal shut before any significant UV-B reaches the ground.

Depletion of the ozone layer is a problem, a symptom of which is this tends to make the ozone hole larger and last longer.

There are many different types of cancers, and they can affect any organ in the body. The most common cancers that affect men are prostate cancer, lung cancer, and colon cancer. The most common three that affect women are breast cancer, colon cancer, and lung cancer. There are many other types than those though.

1) The introduced molecules Shut-Down carcinomas; and/or

2) the introduced therapeutic molecules shut-down the carcinoma's blood-supply; and

3) treatments are becoming more and more specific.

A medicine which destroys cells, such as chemotherapy, usually destroys cells by targeting the mechanisms that cells use for division. They are administered by injection to the bloodstream or as tablets/capsules.
