CAN A CANCER BE CONTAGIOUS? Pregnancy, Infection, and Sex

Cancer is a word that we all are familiar with. It’s the reason we see cancer-related fundraisers and awareness campaigns, and it’s why we might have heard someone say, “You have cancer?”

But what exactly is cancer? What causes it, and how can we prevent it from happening to ourselves?

Cancer is not just a particular disease, but rather a pool of diseases. There are various types of cancers, but they all has defined features which make them similar. Cancer is usually a slow-growing and difficult to treat disease that may affect any part of the body. It’s also one of the most common causes of death in the World, according to the Statistics.  Cancers are caused by three main types: hematologic malignancies like leukemia; solid tumors like breast or prostate cancer; and lymphoma.

Change in DNA of a cell is main cause of beginning of Cancer. Changes are normally called as a process of mutation, and they can be inherited from one of two parent or appear spontaneously in a child.

Cancer often poses an internal hazard. Cell production can occasionally start to expand at an uncontrollable rate while also evading the body’s built-in defenses. If untreated, the lump that results from this is known as a tumour and is typically fatal.



You might have heard that cancer is “contagious.” You might even know that it’s bad to smoke, drink too much alcohol and eat too much junk food. But what about cancer?

Transmissible cancers are rare in humans, but they’re not out of the realm of possibility.

Cancer cells can also travel via the lymphatic system and the digestive system, but these routes don’t typically transfer cancer to other people.

An important exception is when one person passes on a virus that causes cancer in another person. For example, human papillomavirus (HPV) can cause cervical cancers in humans, but it also causes some types of head and neck cancers in dogs.

The cancer has many risk factors that causes it such as your age and sex. For example, you’re more likely to get lung cancer if you smoke or are exposed to asbestos. But it doesn’t mean that everyone who does will develop lung cancer. If one or both members of your family have had certain types of cancers, such as breast or colon cancer, you may be at increased risk for these cancers yourself.

While viruses and bacteria can migrate outside of their hosts, tumours often cannot. The innate immune system, which protects against tissues like cancers that originate from other people or animals, is built into human bodies so they may reject alien cells.

But then this’s not always the case in animals, where there are a few kinds of cancer that can be transmissible and never to humans. And some viruses can lead to cancer, making them an indirect mechanism of cancer Transmission.

In the last few years, however, some research has shown that tumors can be transplanted from one person to another with surprising success. The cell lines are still kept separate, but the idea is that some sort of signal — perhaps a protein on the tumor cells or an antibody in the recipient — will cause them to recognize each other as family members and fuse together.

Research done decades before by the cancer researcher Chester Southam had confirmed this. When he attempted to place tumors from cancer patients into healthy recipients, the cancerous cells typically melted away, killed off by the recipient’s immune systems.



While it is true that cancer can be passed on to your child, the chances of this happening are extremely low.

There is very little possibility that you may give birth to a child with cancer. Even developing cancer while pregnant is extremely uncommon, occurring in only approximately 1 in every one thousand pregnancies. 

While your baby is in the womb, cancer can spread to the placenta, although research shows that this is incredibly uncommon.


The most important thing to know about the risk of cancer is that it’s not caused by something you can catch or make yourself sick from. There are several types of cancer, including skin cancer, breast cancer, colon cancer and prostate cancer.

If you or your parents have a hereditary cancer, there are steps you can take to increase your chances of developing cancer.

  • Don’t smoke, and never do secondhand smoke.
  • Create a balanced diet, which includes fruits, vegetables, whole grains, and low-fat dairy products.
  • Drink alcohol in moderation.
  • Exercise regularly.
  • Get plenty of sleep every night.
