Cancer, one of the deadliest diseases known to humankind, is often thought of as a result of genetic mutations or environmental factors. However, there are certain cancer types that have the ability to spread from one individual to another.

Just like any infectious disease, these contagious cancers can be transmitted through direct contact, bodily fluids, or even simple physical interaction. In this article, we will explore six contagious cancers that you should be aware of, understand their transmission methods, and discuss the preventive measures that can help reduce the risk of contracting these unique forms of cancer.

1. Tasmanian Devil Facial Tumor Disease (DFTD)

Tasmanian devils, native to the Australian island of Tasmania, have been facing a devastating crisis due to the spread of Tasmanian Devil Facial Tumor Disease (DFTD).

This highly contagious cancer is transmitted through direct contact during physical interactions, such as biting or scratching. The tumors, which primarily affect the face, mouth, and neck of the devils, spread rapidly, leading to death in almost all infected individuals.

Efforts are being made to manage and control the spread of DFTD by implementing quarantine measures for infected individuals and promoting genetic diversity within captive populations.

2. Canine Transmissible Venereal Tumor (CTVT)

Dogs, often referred to as humans’ best friends, can also suffer from contagious cancers. Canine Transmissible Venereal Tumor (CTVT), also known as Sticker’s sarcoma, is a sexually transmitted cancer that affects canines worldwide.

This contagious cancer is primarily transmitted through the transfer of tumor cells during sexual contact. In rare cases, it can also be transmitted through sniffing or licking an infected individual’s tumor. The tumor cells can grow on various parts of the dog’s body, including the genital area, mouth, and nose.

To prevent the spread of CTVT, spaying and neutering are recommended, along with responsible sexual behavior management in dogs.

3. Devil Facial Tumor Disease (DFTD)

Another contagious cancer that affects marsupials, particularly Tasmanian devils, is Devil Facial Tumor Disease (DFTD).

Similar to its cousin, Tasmanian Devil Facial Tumor Disease (DFTD), this contagious cancer spreads through direct contact during social interactions. The tumor cells primarily affect the devils’ face and mouth, causing significant facial deformities, difficulties in eating, and ultimately leading to death.

Conservation organizations and researchers are dedicated to finding ways to manage the spread of DFTD, including captive breeding programs and vaccination trials.

4. Canine Oral Papillomatosis

Canine Oral Papillomatosis is a contagious viral disease that primarily affects young dogs. It is caused by the canine oral papillomavirus, which spreads through direct contact with infected animals or contaminated objects.

This contagious cancer is characterized by the formation of benign tumors in the mouth, throat, and tonsils of dogs. These tumors may cause discomfort and difficulties in eating. The immune system of most affected dogs is capable of eliminating the virus over time. However, in rare instances, the tumors may persist and require veterinary intervention.

Regular vaccination and maintaining good hygiene can help prevent the transmission of Canine Oral Papillomatosis.

5. Devil Facial Tumor Disease (DFTD) in Other Marsupials

The contagious cancer known as Devil Facial Tumor Disease (DFTD) does not only affect Tasmanian devils but also other marsupials, such as quolls and bandicoots.

These small mammals become susceptible to the disease through bites and scratches during territorial disputes or mating encounters. As with Tasmanian devils, the tumor cells primarily affect the face and mouth of the infected marsupials, leading to severe complications and often death.

Research is ongoing to better understand the transmission dynamics and develop targeted approaches to control the spread of DFTD in diverse marsupial populations.

6. Contagious Burkitt Lymphoma

Burkitt lymphoma is a type of non-Hodgkin lymphoma that predominantly affects children in equatorial Africa. The endemic form of Burkitt lymphoma in this region is caused by the Epstein-Barr virus (EBV) and is highly contagious.

The transmission occurs through oral contact, such as sharing food or drinks contaminated with EBV-infected saliva. The contagious Burkitt lymphoma primarily manifests as a rapidly growing tumor in the jaw or abdomen.

Preventive measures, such as improving sanitation, promoting good oral hygiene, and increasing access to healthcare, are crucial in reducing the transmission and impact of this contagious cancer.

Conclusion

Contagious cancers might sound like something out of a horror movie, but they are unfortunate realities that affect various species, including humans.

These unique forms of cancer can be transmitted through direct contact, bodily fluids, or close interaction, posing significant challenges in their prevention and management. Understanding the transmission methods and implementing preventive measures are crucial steps in minimizing the risk of contracting these contagious cancers.

By further researching these diseases and raising awareness, we can hope to develop effective strategies to combat their spread and alleviate the suffering they cause.
