Cancer

The pink ribbon represents awareness and support for breast cancer. It is a symbol of solidarity for those affected by the disease, as well as a reminder of the importance of early detection and the need for research and funding to find a cure.

Leukemia is a type of cancer that results in an overproduction of abnormal white blood cells in the bone marrow. This leads to a decrease in the production of normal blood cells and can cause a lack of healthy white blood cells.

The basic idea behind radiation therapy is very simple; destroy the cancer cells. Gamma Rays and Beta Rays (electrons) are very good at killing cells by tearing apart the molecules that make up the cell. Just like shooting someone with a bullet, but on a much smaller scale. The problem is that radiation also kills good cells so you just can't radiate the whole body. The radiation beam has to be aimed at the cancer and the dosage as small as possible.

---- Also there's a limit to how fast you can kill the tumour with radiation. The lysis products of even a small tumour can make you very ill if the concentration in your bloodstream becomes high.

The process of cancer cells growing and replacing healthy cells is called metastasis. This occurs when cancer cells spread from the original site of the tumor to other parts of the body, allowing them to invade and replace healthy tissues.

People with Breast cancer may consider avoiding certain foods or making dietary changes to support their overall health and well-being during treatment. Here are some foods that they may want to limit or avoid:

Processed Meats: Foods like bacon, sausages, Hot Dogs, and deli meats contain nitrates and nitrites, which have been linked to an increased risk of cancer.

Sugary Foods and Beverages: High-sugar foods and drinks can contribute to weight gain and insulin spikes, which may promote cancer growth. Limiting sugary snacks, sodas, and desserts is advisable.

Alcohol: Alcohol consumption has been linked to an increased risk of breast cancer. It's recommended to limit or avoid alcohol, especially during cancer treatment.

Fried and Fast Foods: Foods that are high in unhealthy fats, such as fried foods and fast food items, can contribute to inflammation and weight gain, which may negatively impact cancer treatment outcomes.

Highly Processed Foods: Processed foods like chips, cookies, cakes, and ready-to-eat meals often contain unhealthy fats, sugars, and additives that may not be beneficial for overall health and cancer recovery.

Excessive Red and Processed Meats: While lean cuts of red meat can be part of a balanced diet, excessive consumption of red and processed meats has been associated with an increased risk of cancer. It's advisable to consume these in moderation.

Soy Products (in Some Cases): Some breast cancer patients may be advised to limit soy products due to their phytoestrogen content, which can mimic estrogen in the body. However, this recommendation may vary based on individual factors and should be discussed with healthcare providers.

Overall, a balanced diet rich in fruits, vegetables, whole grains, lean proteins, and healthy fats is beneficial for people with breast cancer. It's important for individuals to work with healthcare providers and nutritionists to develop a personalized dietary plan that supports their specific needs during treatment and recovery.

If the rate of repair lags behind the rate of mutation, the cell may accumulate DNA damage that can result in genomic instability. This can lead to an increased risk of developing cancer or other diseases.

Inheriting a mutated cell cycle gene and engaging in risky behaviors like sunbathing can increase your risk of developing cancer, but it does not guarantee that you will definitely get cancer in the future. Your risk is higher, so it's important to take steps to reduce your risk by practicing sun safety and getting regular check-ups with a healthcare provider.

Cancer cells can be engulfed by immune cells in the body, preventing them from spreading. Swallowing cancer cells would not cause cancer in the person because cancer is not a contagious disease that can be transmitted through ingestion. However, it is important to focus on prevention and early detection of cancer through healthy lifestyle habits and regular screenings.

Malignant tumors, such as carcinomas and sarcomas, are characterized by invasive cells that proliferate uncontrollably and have the ability to spread to surrounding tissues. These tumors have the potential to metastasize, forming secondary tumors at distant sites in the body, making them a serious threat to the patient's health.

Essential thrombocythemia is a rare blood disorder characterized by the overproduction of platelets in the bone marrow. The specific cause is unknown, but it is thought to be related to genetic mutations affecting the cells responsible for platelet production. Factors such as age and family history may also play a role in its development.

The thinning of the ozone layer would cause great harm to skin cancer because the sun which is currently getting closer, would put mor UV rays into the earth affecting peoples skin. This is why sunscreen was created because it would be a time when they need it and the tim has come. They still use it to protect from sun but you cane read on the package it says helps "UV rays". Lessomn: Always where sunscreen expetially because the zone hole is depleting and is causing great harm.

A tumor arising from an astral cell is called an astrocytoma. Astrocytomas are a type of brain tumor that originates from astrocytes, which are a type of star-shaped glial cell in the brain and spinal cord.

Leukemia is a type of cancer that starts in the bone marrow and results in the overproduction of abnormal white blood cells. Leukemoid reaction, on the other hand, is a reactive increase in white blood cells in response to an underlying infection or inflammation, but it is not a malignant condition like leukemia.

When looking for supplements for cancer, start with the well-known antioxidants including Vitamins A, C & E,. They are especially valuable in fighting cancer.

Vitamin A, better taken as beta carotene protects against breast, bladder, colon & lung cancer. Take at least 10,000 IU of beta carotene daily.

Vitamin C, what I think of as the master vitamin, so no surprise that it is also an important cancer fighting vitamin. It especially protects against breast, colon & lung cancer. Take between 5,000 - 10,000 mgs in divided doses as the body excretes Vitamin C pretty quickly.

Vitamin E helps prevent stomach cancer and other gastrointestinal cancers. Take between 400 - 1,000 IU daily with meals.

Selenium, which is a heavy metal and harmful in excess amounts, is a powerful antioxidant. Selenium is thought to protect against breast, colon & lung cancer. Take 200 mcg daily.

Calcium, is also one of the better supplements for cancer prevention. A very important mineral, it prevents colon cancer & polyps which are precancerous matter. Take between 500 - 1500 mgs daily.

The amino acid, arginine, promotes release of growth hormone which, essentially is a hallmark of youth. This lowers risk of cancer formation. Makes sense since youngsters rarely develop cancer. Take as directed.

Folic acid lowers the risk of colon & breast cancer. Take 400 mcg of folic acid daily.

Finally, lycopene is a phytochemical found in colorful fruits and veggies. Lycopene is thought to lower incidence of bladder & pancreatic cancer. Take according to package directions.

Neoplasia refers to the growth of abnormal cells. When those cells form a mass, that mass is called "neoplasm".

In neoplasia the cells are produced uncontrollably, meaning, more of them are produced as needed, and they have less time to differentiate (mature) into proper, functional cells.

Neoplasm are considered to be either benign (not malignant), or malignant (cancerous)

Benign neoplasm:

- the cells produced more slowly,

- have more time to differentiate, (cells are more able to function)

- the proliferation (cell production) might even stop or revert

- the formed mass could be enclosed in a capsule, (which could prevent spreading = metastasis)

- might only be one mass.

Malignant neoplasm:

- cells produced rapidly,

- have less time to differentiate (cells can't function)

- does not have a capsule,

- the mass invades the neighbouring tissues

- cells can break off, carried away by blood

- break off cell stops at other part of the body, where it starts an another mass (secondary tumour).

Haematologic cancers (cancers affecting blood cells) do not form a mass, the blood cells would incontrolably proliferate.

While the nature of the neoplasm could be differentiated as above, many health professionals do not regard neoplasm as "non-cancerous".

Apoptosis might be seen as part of the body's overseeing/managing/protecting mechanism.

Apoptosis is associated with cell death; a programmed cell death, where "abnormal" cells, which either cannot function properly (aged, injured, etc), or are potential threat to the organism (infected, mutated), have to die.

By activating apoptosis of those cells, the body stops their proliferation. If this mechanism gets impaired (for example tumour suppressor genes, like p53, cannot promote apoptosis), the uncontrolled proliferation of the abnormal cells could lead to malignancy.

Cancer cells are abnormal cells that divide uncontrollably and can invade nearby tissues, whereas old cells are normal cells that have reached the end of their lifespan and stop dividing. Cancer cells can cause tumors and metastasize, while old cells are usually cleared away by the immune system.

Mitosis is a form of cell division. Cancer is a mutation in cell division, generally in such a way that cell divide too often and are unregulated and end up developing a mass. Those cells also carry the mutation and those cells divide and create new mutated cells, on and on and on.

The immune system plays a crucial role in detecting and destroying cancer cells before they can cause harm. Certain treatments such as chemotherapy, radiation therapy, and targeted therapy are also used to kill cancer cells. Additionally, early detection of cancer through screenings can enable timely intervention to remove or destroy cancerous cells.

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.
