Which Of The Following Infectious Agents Are A Causative Factor For Cancer

What is cancer, and how is it diagnosed?

Cancer is defined as a disease.

Cells in the body proliferate uncontrolled in cancer, which then spreads throughout the body. The human body is made up of billions of cells, and cancer may begin in any one of these cells.

Hepatitis B causes cancer in what way?

Because of the hepatitis B virus’s ability to replicate and thrive in the human body, it may induce cirrhosis without ever producing hepatitis (inflammation of the liver). The virus, on the other hand, has the potential to harm the DNA of liver cells, resulting in cancer.

What’s the most contagious sickness you’ve ever heard of?

The bubonic and pneumonic plagues are sometimes cited as the origin of the Black Death, a pandemic that ravaged Asia, Europe, and Africa in the 14th century, killing an estimated 50 million people. They are among the most renowned infectious illnesses.

What kind of cancer is contagious?

Cancer is not spread by others.

In order to get cancer, you must have it yourself. A cancer cannot be communicated by intimate acts of intercourse or other forms of physical intimacy like kissing, holding hands or sharing a meal with another person. It is impossible for cancer cells from a cancer patient to survive in the body of a healthy individual.

What are the four main categories of illnesses, and how many are there?

Maladies may be divided into four broad categories: infectious, deficient, hereditary, and physiological (covering both genetic and non-genetic hereditary disorders).

What is the scientific name for viruses that cause cancer?

Oncoviruses, or cancer-causing viruses, are many. EBV is a herpes virus that may be transmitted by saliva. Stomach cancer and some forms of Hodgkin’s and non-lymphomas Hodgkin’s are all made more likely by infection with the Epstein-Barr virus (EBV).

Is cancer an illness that is not contagious?

There are several chronic non-communicable illnesses that have similar risk factors and whose prevention and treatment would benefit most of the world’s population, including cancer.

In the context of infectious illness, what exactly do we mean by the term “host”?

By “host,” we mean any living entity that serves as a safe haven for an invading pathogen, generally one that is parasitic. 1. A sexually developing organism may partly or entirely rely on a host for refuge or nutrition.

Is it possible that cancer might be spread from person to person?

Cancer is not spread by others.

In order to get cancer, you must have it yourself. A cancer cannot be communicated by intimate acts of intercourse or other forms of physical intimacy like kissing, holding hands or sharing a meal with another person. It is impossible for cancer cells from a cancer patient to survive in the body of a healthy individual.

What oncogenes may be activated by transcription factors?

Transcriptional factor AP-1 To trigger transcription of growth factor-inducible genes, Fos and Jun create AP-1. In certain human malignancies, G protein-coupled receptors and G proteins are also oncogenes (Figure 15.29).

What causes the spread of cancer?

When cancer spreads throughout the body, the primary cause is an alteration in DNA. A cancer cell’s genome (the DNA contained in its nucleus) might become aberrant due to a mutation or other abnormalities, causing it to become isolated from its neighbours and invade nearby tissue.

Is there a link between cancer and infectious agents?

Viruses, bacteria, and parasites are all examples of infectious agents that have the potential to cause cancer or raise one’s chance of developing cancer. Viruses have the ability to interfere with the regular signalling pathways that regulate cell development and proliferation.

What is the role of DNA viruses in the development of cancer?

There are many different types of viruses, infections, and cancer.

When a virus causes an infection, its DNA is distributed throughout the body, possibly causing healthy cells to become cancerous. Virus infections, such as those caused by HPV, may lead to a fusion of the virus’ DNA with the host’s DNA, resulting in cell dysfunction.
