Colon cancer-causing ulcers and polyps can now be visually diagnosed. A collection of abnormal cells is known as a polyp carcinogen.
<h3>Explain about the
polyp carcinogen?</h3>
If given the chance to develop over time, these polyps could develop into cancer. The term adenomas refers to the majority of these colon polyps. The size and location of the serrated polyps in the colon will determine whether they develop into cancer. Generally speaking, neoplastic polyps have the highest risk of malignancy among all polyp sizes.
A tissue growth that protrudes from the colon or rectum is referred to as a colorectal polyp. Although benign (i.e., not cancerous) and non-proliferating, some forms of polyps have the potential to turn malignant over time. The term "adenomatous polyps" refers to one of these varieties. We refer to these as pre-cancerous polyps.

The body's first line of defense is actually the non-specific immune system which is also called innate immunity.
Innate immunity employs both physical and chemical barriers that form the first line of defense. These include:
1. The intact skin. The skin is made up of keratin in its outermost layer. Keratin makes skin tough and resistant and pathogens usually cannot penetrate unless the skin is broken.
2. The mucus membrane. This is a thin membrane that forms a protective lining inside many organs and other parts of the body such as the trachea. Mucus produced by the membrane traps bacteria and other harmful particle which are then expelled from the body.
3. Tears. Tears from our eyes contain lysozyme, a chemical that kills bacteria.
If the pathogen gets through or evades these types of defenses, then it is dealt with by the second line of defense which is called specific immunity or acquired immunity. It is here that white blood cells namely the B lymphocytes and T lymphocytes attack, kill or neutralize pathogens.
