Where does the equator and tropic of cancer meet?

User Avatar

Asked by Wiki User

They DON'T meet. They are concentric parallel lines of latitude.

The Equator is 0 (Zero) degrees of latitude.

The Tropic of Cancer is 23.3 degrees N line of of latitude.

The corresponding Tropic oin the Southern Hemishere is the Tropic of Caprocorn at 23.3 degrees S line of latitude.

On the Globe/sphere/Earth the lines of latitude are parallel lines on the surface.

Being parallel lines they do NOT meet.

Do cancer cells have MHC?

User Avatar

Asked by Wiki User

Yes, cancer cells can have major histocompatibility complex (MHC) molecules, which play a role in immune recognition. However, cancer cells can also downregulate MHC expression as an immune evasion strategy.

What are tumor cells monoclonal kappa light chain positive?

User Avatar

Asked by Wiki User

Tumor cells that are monoclonal kappa light chain positive express a specific type of immunoglobulin light chain on their surface. This finding is often seen in certain types of B-cell lymphomas or multiple myeloma, indicating that these tumors are derived from a single clone of B-cells that produce this specific light chain. Detection of monoclonal kappa light chain positivity helps in diagnosis and monitoring of these conditions.

How can a proto oncogene be converted into an oncogene without a change or mutation in its coding sequence?

User Avatar

Asked by Wiki User

A proto-oncogene can be converted into an oncogene through mechanisms such as gene amplification, chromosomal rearrangements, or altered regulation of gene expression without changes in its coding sequence. These alterations can lead to increased expression or activity of the proto-oncogene, resulting in uncontrolled cell growth and division characteristic of cancer cells.

What causes a oncogene to form that changes normal cells into cancerous cells?

User Avatar

Asked by Wiki User

Oncogenes can form through various mechanisms, such as genetic mutations, gene amplification, or chromosomal translocations. These alterations lead to the dysregulation of cell growth and division, ultimately transforming normal cells into cancerous cells. Oncogenes encode proteins that promote uncontrolled cell proliferation, survival, and invasion, contributing to the development and progression of cancer.

How did Marie Curie's discovery of Radium help kill cancer?

User Avatar

Asked by Wiki User

Marie Curie's discovery of radium paved the way for the development of radiation therapy to treat cancer. Radium emits high-energy radiation that can target and kill cancer cells, making it a valuable tool in cancer treatment. Today, radiation therapy is a common method used to shrink or destroy tumors in the body.

Do cigarette filters cause cancer?

User Avatar

Asked by Wiki User

Cigarette filters don't directly cause cancer, but they don't eliminate health risks either. They may reduce exposure to some toxins but can still cause cancer due to the harmful chemicals inhaled while smoking. Quitting smoking entirely remains the best way to reduce cancer risk associated with cigarettes.

How is mutation related to cancer development?

User Avatar

Asked by Wiki User

Mutations can lead to uncontrolled cell growth and division, which is a hallmark of cancer. Mutations in genes that regulate cell proliferation, cell death, and DNA repair can disrupt normal cellular processes, promoting the development of cancer. In some cases, accumulated mutations may give cells a growth advantage, allowing them to form tumors and eventually metastasize.

Who is the best oncologist in the world?

User Avatar

Asked by Wiki User

It is not possible to definitively determine who the best oncologist in the world is, as expertise and success in treating cancer can vary based on the type of cancer, patient needs, and location. Numerous oncologists around the world are highly skilled and respected in their field. It is important to research and find an oncologist that specializes in the specific type of cancer you are dealing with.

Where are cancer cells found in the body?

User Avatar

Asked by Wiki User

Cancer cells are found in the affected organ or tissue. There are several types of cancer depending on anatomical location within the body like skin cancer, blood cancer, lung cancer etc. Also it depends on how a particular type of cancer spreads like the Carcinomas spread through lymph so the cancer cells can be found at lymph nodes whereas, the sarcomas spread through blood. Another noteworthy thing is that in the later stages of cancer it can spread to a distant organ and start a secondary cancer in the new location.

What part of the cell cycle is decreased in cancer cells?

User Avatar

Asked by Wiki User

The G1 phase of the cell cycle is often decreased in cancer cells, leading to uncontrolled cell growth and proliferation. This can result in rapid tumor formation and progression.

What is an example of a carcinogen Asbestos Benzene Argon or Formaldehyde?

User Avatar

Asked by Wiki User

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

What causes a person to have cancer?

User Avatar

Asked by Wiki User

Cancer is caused by genetic mutations that lead to uncontrolled cell growth. These mutations can be acquired through factors like smoking, ultraviolet radiation, and certain viruses, or inherited from family members. Other factors such as age, diet, and environmental exposures can also contribute to the development of cancer.

How is cancer related to cell divisions?

User Avatar

Asked by Wiki User

Cancer is related to cell divisions because it results from uncontrolled and abnormal cell division. When cells divide uncontrollably, they can form a mass of tissue known as a tumor. Cancer can develop when these abnormal cells continue to divide and spread to other parts of the body.

Is cancer a disease of the cell division or the circulatory system?

User Avatar

Asked by Wiki User

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.

What is the difference between invasion of cancer cells and metastasis of cancer cells?

User Avatar

Asked by Wiki User

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.

What are cells that are not cancerous and have no affect on health called?

User Avatar

Asked by Wiki User

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.

What is P53 and what does it have to do with cancer?

User Avatar

Asked by D4est

P53 is a tumor suppressor gene that plays a critical role in preventing the growth of cancerous cells. It regulates cell division and DNA repair, helping to maintain the integrity of the genome. Mutations in the P53 gene can lead to uncontrolled cell division and are commonly found in many types of cancer.

Is it true cancer does not develop in space?

User Avatar

Asked by Wiki User

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.

Can you explain the way an abnormal p53 causes normal cells to become cancer cells?

User Avatar

Asked by Wiki User

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.

How long of cancer did it take to kill Marie curie?

User Avatar

Asked by Wiki User

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.
