Molecular Pathogenesis of Oral Cancer. Oral carcinogenesis like any other cancer is a progressive disease and normal epithelium passes through stages starting from dysplasia to finally transforming into invasive phenotypes. Although all types of carcinomas are seen in oral cavity, the most common form of OC is squamous cell carcinoma mary cause of cancer, and the pathogenesis of cancer is seen as a process of transformation of a normal cell into a tumor cell, as evidenced by deep fundamental research of the pathogenesis of cancer, which is held exclusively at the cellular, molecular and genetic levels of the organism [1] [2]. Such a vector of the scientific researc

The development of oral squamous cell carcinoma (OSCC) is a multistep process requiring the accumulation of multiple genetic alterations, influenced by a patient's genetic predisposition as well as by environmental influences, including tobacco, alcohol, chronic inflammation, and viral infection. Tu Pathogenesis of Cancer Biological Basis of cancer Cancer is the uncontrolled growth and spread of abnormal cells in the body. Cancers (malignant neo-plasms) can arise from virtually any tissue and are usually named by the anatomic site of origin. Exam-ples include breast cancer, prostate cancer, colon cancer, and lung cancer, the four cancers. The term 'oral cancer' describes a range of malignancies that may arise in and around the oral cavity. Over 90% of such lesions are squamous cell carcinomas, but even these may be divided into.

Cervical Cancer: an Avoidable NCD with Gross Inequities. 528,000 new cases. 266,000 death. 90 % of the deaths in LMIC. Cervical cancer is an unacceptable disease and the burden is still far too high in many countries, principally in middle and low income countries, reflecting the many inequities across the world in terms of access to services Cancer pathophysiology. Regardless of difference in types of cancer histologically and physiologically, there is existence of a common pathophysiological process of malignant tumors or cancer development in the organism. The commonly accepted basis of the pathogenesis of cancer is the damage to the geneti

Mouth (oral) cancer is a major neoplasm worldwide and accounts for most head and neck cancers. Theoretically, it should be largely preventable or detectable at an early stage, given that the mouth is easy to access and examine by patients and healthcare professionals, assuming they have good lighting. [] Approximately 90% of oral cancers are SCC, which is seen typically on the lateral border. PATHOGENESIS. OLP is a T-cell mediated autoimmune disease in which the auto-cytotoxic CD8+ T cells trigger apoptosis of the basal cells of the oral epithelium.[] An early event in the disease mechanism involves keratinocyte antigen expression or unmasking of an antigen that may be a self-peptide or a heat shock protein.[1,6] Following this, T cells (mostly CD8+, and some CD4+ cells) migrate.

There are three mechanisms of action of oral microbiota in cancer pathogenesis, chronic inflammation of bacterial stimulation, carcinogenesis by cytoskeletal rearrangements, and carcinogenic substances that produced by microorganisms. Changes in the composition of microbiota could therefore have the potential to be used as a significant oral. Colorectal cancer is also called colon cancer or rectal cancer. It refers to any cancer in the colon from the beginning (at the cecum) to the end (at the rectum). Colorectal cancer occurs when cells that line the colon (large bowel, large intestine) or the rectum (lower portion of the colon) become abnormal and grow out of control Pancreatic cancer that blocks the liver's bile duct can cause jaundice. Signs include yellow skin and eyes, dark-colored urine, and pale-colored stools. Jaundice usually occurs without abdominal pain.

Oropharyngeal cancer is a type of head and neck cancer in which cancer cells are found within an area of your throat called your oropharynx. More than 90% of oropharyngeal cancers are squamous cell carcinomas, which are cancers arising from the flat surface cells lining your mouth and throat Changes in the oral microbiome have been proposed to contribute to oncogenesis in the 7-15% of oral cancer cases, which cannot be explained by known risk factors 182,183,184 Pathophysiology. The endometrium is the mucous membrane layer that lines the inside of a female's uterus. This is the portion of the uterus that changes throughout the menstrual cycle, becoming thick and rich with blood vessels to prepare for pregnancy, then shedding if the woman does not become pregnant (Burney & Giudice, 2012)

  1. Uterine leiomyomas (fibroids or myomas) are benign tumors of uterus and clinically apparent in a large part of reproductive aged women. Clinically, they present with a variety of symptoms: excessive menstrual bleeding, dysmenorrhoea and intermenstrual bleeding, chronic pelvic pain, and pressure symptoms such as a sensation of bloatedness, increased urinary frequency, and bowel disturbance
  2. Epidemiology. Overall, the incidence of cancer is higher in men than in women and higher in industrialized sectors and nations.. More than 1.4 million Americans are diagnosed each year with cancer, affecting one of various body sites.; Cancer is second only to cardiovascular disease as a leading cause of death in the United States.; Although the number of cancer deaths has decreased slightly.
  3. Lung Cancer Pathogenesis. Multistep tumorigenesis, in which tumors develop through a series of progressive pathologic changes (preneoplastic or precursor lesions) with corresponding genetic and epigenetic aberrations, has been demonstrated in various organs, including the skin, lung, and colon ().Hyperplasia, squamous metaplasia, squamous dysplasia, and carcinoma in situ (CIS) comprise changes.

The uterus functions to support fetal development until birth. The uterus is shaped like an upside-down pear; the top is the fundus, the middle is the corpus, and bottom is the cervix; the inner layer of the uterus is the endometrium.

include certain viral infections, poor oral hygiene, and workplace-related exposures, such as radiation. The clinical presentation depends on the location of the tumor. Symptoms may include a growing cervical lump, persistent sore throat, , or a change in the voice. Diagnosis is confirmed based on tissue Accumulating studies have indicated that long non-coding RNAs (lncRNAs) participate in the regulation of cancer stem cells (CSCs), which are crucial in tumor initiation, metastasis, relapse, and therapy resistance. In the current study, RT-PCR analysis was employed to evaluate the expression of LINC00963 in tumor tissues and oral CSCs. Stemness phenotypes and the expression of CSCs markers in. The risk of lung, oral, and other cancers can be reduced by quitting smoking. Because HIV-infected people have a higher risk of lung cancer, it is especially important that they do not smoke.

Oral candidiasis is a common opportunistic infection of the oral cavity caused by an overgrowth of Candida species, the commonest being Candida albicans . The incidence varies depending on age and certain predisposing factors. There are three broad groupings consisting of acute candidiasis, chronic candidiasis, and angular cheilitis. Risk factors include impaired salivary gland function, drugs. Carcinoma in situ of the oral cavity is found in less than 1% of men under 30 years of age. Up to 8% of men over 70 years of age and 2% of women over 70 years of age have carcinoma in situ of the oral cavity. It is rare before age 30 and peaks after 50 years.

Pathogenesis may occur through the integration of viral genetic elements into host DNA. These new genes are expressed by the host; they may affect cell growth or division or disrupt normal host genes required for control of cell growth and. Oncoviruses are implicated in approximately 12% of all human cancers. A large number of the world's population harbors at least one of these oncoviruses, but only a small proportion of these individuals go on to develop cancer. The interplay between host and viral factors is a complex process that works together to create a microenvironment conducive to oncogenesis
