Oncology Specialist Prof. Dr. Hakan Karagöl explained that this situation was determined when babies pass through the birth canal during birth, when cancer cells in the uterus and cervix enter the baby’s mouth and escape into the lung trachea.


Oncology specialist Prof. Dr. Hakan Karagöl said that various types of viruses, bacteria, organ transplants and births show that cancers can be transmitted from person to person. Reminding that the cancer patient touches a healthy person, shares his food with him, is not transmitted through the air inhaled in the same environment, kissing or sexual intercourse, he shared the following information about the new studies.

“In Japan, it was determined that 2 babies with uterine / cervical cancer in their mother had cancer transmitted from the mother and settled in the lung. In the examinations performed on these babies, lung cancer was detected in one at the 23rd month after birth and the other at the age of 6. It has been determined that this situation occurs when babies pass through the birth canal during birth, and the cancer cells found here enter the baby’s mouth and escape into the lung trachea. ”

Oncologist Prof. Dr. Hakan Karagöl shared the information that cancer develops years after this viral infection.


Underlining that the contamination of multiplying microbe species and the development of cancer over time, Prof. Dr. Hakan Karagöl shared the following information about these types of microbes in which different types of cancer can develop in various ways;

Human Papilloma Virus, which is transmitted by sexual intercourse and causes cervical cancer, spreads from one person to another and is the most important cause of cervical cancer in South Asia and South America.

-The microbe called Epstein Barr Virus and causing kissing disease can cause throat cancer and lymph node cancer.

Hepatitis B and C viruses, which are transmitted from one person to another by blood, body secretion or sperm, and cause inflammation in the liver, can cause liver cancer.

AIDS virus can cause a type of cancer called Kaposi’s sarcoma.


Stating that bacteria in the cellular structure can also be transmitted from person to person and can cause cancer, Prof. Dr. Hakan Karagöl stated that the best example of this is the Helicobacter pylori bacterium that can cause stomach cancer. Prof. Dr. Karagöl exemplified the fact that parasites formed by the combination of many cells can also cause cancer as follows:

“A parasite called Schistosoma heamatobium, which enters the body from the skin of another person and enters the bladder from human urine mixed with water in wetland, causes bladder cancer,” he said.


Stating that in the literature studies, it was found that 5 out of 10,000 organ transplant people may have donor-related cancer contamination. Dr. Hakan Karagöl said that this situation occurred after organ transplants from a cancer patient. One of the most striking examples of this is that all 4 people who received 4 different organs from a female donor who was thought to have no cancer in Europe in 2007 and died due to a cerebral hemorrhage were seen with breast cancer with features similar to each other. After the evaluation, it was understood that the breast cancer seen in these 4 recipients was due to the transmission of breast cancer in the donor woman but not seen in the tests. Emphasizing that the donors whose organ will be transplanted should be examined in terms of cancer, Prof. Dr. Hakan Karagöl explained how the contamination took place as follows;

” If there is cancer in the donor, the recipient who receives the organ from the donor should use immunosuppressive drugs after the organ transplantation, in order to prevent rejection from the body due to the resistance of the immune system of the given organ. With the suppression with this drug, cancer cells hidden in the organ taken from the donor cannot be destroyed by the recipient’s immune system, and they begin to multiply and spread in the body of the recipient. ”


Stating that another way of direct transmission of cancer from person to person is cancer that passes to babies during pregnancy, Prof. Dr. Hakan Karagöl stated that cancer can be passed from mother to baby in one out of every 500,000 births. In a literature review published in 2002, she stated that some of the mothers with cancer were shown to be able to get the mother’s cancer through blood while their babies were still in the womb, and shared the following information about the study;

It has been stated that the cases of cancer transmission from 67 mothers to the baby during pregnancy have been reported in the world and the vast majority of these are related to the blood cancer of the mother and the skin cancer called malignant melanoma. In another case, the baby of a mother with lung cancer in the last three months of her pregnancy, there was no problem in the birth but a mass developed in the brain a few months after the birth, the examination revealed that this mass was lung cancer spread but there was no disease in the baby’s lung, these cancer cells seen in the baby’s brain During pregnancy, it was thought to be transmitted from the mother to the baby’s bloodstream and into the baby’s brain. In two newly published cases of baby cancer in Japan, it was determined that the baby swallowed the cancer cells in the mother’s uterus and escaped into the trachea while the baby was passing through the birth canal. ”
