Basics of Cervical Cancer: Secret Origin and Development
Cervical cancer is a common malignant tumour in gynaecology, which seriously threatens the health of women. Understanding its origins and development can help us to better understand the disease and to raise awareness about prevention.
I. Origin of cervical cancer
Cervical cancer occurs mainly as a result of abnormal changes in cervix skin cells. The cervix is like the “door” of the uterus, with two types of upper-skin cells: the skin of the slab and the skin of the column, while the “source” of cervical cancer is often hidden in these upper-skin cells.
Human papilloma virus (HPV) infection: this is the most critical cause of cervical cancer. HPV is a very common virus with many subtypes. Among them, some high-risk HPVs, such as HPV16, HPV18 and others, can cause pathologies if they continue to be infected with cervix cells. These viruses integrate their genes into the DNA of the cervix skin cells, interfere with the normal functioning of the cells, render cell proliferation uncontrollable, as they add to the “operational procedures” of the cells and take the first steps towards a cancerous cell.
CIN: After HPV infection, some abnormal changes occur in the cervix cell, which is the cervix. It can be divided into different levels, with CIN I being mildly abnormally increased, with smaller heterogeneity of cells; CIN II being moderately abnormally increased; and CIN III being severely abnormally increased and in situ cancer. At this stage, the pathology is confined to the top of the cervix, which has not yet reached the base membrane and immersed in deep tissues, as if cancer cells were still trapped in “cages”, but there are obvious anomalies.
II. Development of cervical cancer
When cervix mesothelioma has developed to a certain extent, especially CIN III, it may be further developed to impregnated cervical cancer if it is not treated in a timely and effective manner.
Cervical immersion: At this point, cancer cells break through the substrate of the top of the cervix and begin to impregnate to the meme of the cervix and the surrounding tissue. Over time, cancer cells will spread and the impact will increase.
In the early stages of immersion of cervical cancer, the symptoms may not be obvious, but there is only occasional and irregular vaginal bleeding, such as a small amount of bleeding after sexual intercourse, after gynaecology or in the non-menstrual period. This is due to cancer cells violating the cervix ‘ s blood vessels, which cause the blood to split.
As the condition evolves, there will be an increase in vaginal discharges in addition to the irregular bleeding of the vagina. Ejected liquids may be white or bloody, thin as water or rice, and smelly. This is because cancer cells produce some unusual secretions during growth, excreted through the vagina.
Transfer: Cervical cancer has developed to a certain stage, and cancer cells have transmissible properties. They can be lymph cycling to pelvic lymph nodes, causing lymph nodes to swell. Further, the transfer of blood circulation to other parts of the body, such as the lungs, the liver, the bones and so on, has led to pathologies in these remote areas, which will make treatment more difficult.
Cervical cancer is an evolving process from its origins to its development. With this knowledge, female friends are able to place greater emphasis on the prevention of cervical cancer, such as active vaccination against HPV, regular screening for cervical cancer, etc., and, in the event of early detection of a disease and timely treatment, are able to effectively reduce the incidence of cervical cancer and improve its cure and protect their health.
