Are Seborrheic Keratosis Contagious?

Seborrheic keratosis is a common benign growth that is round or oval and range in size from small to more than 2.5cm. They are seen most often as people age and cannot be prevented because there are no exact causes for them. They are said to occur due to genetic reasons and extreme exposure to the sun. One thing about seborrheic keratosis is that, it does not hurt or cause pain and is rarely dangerous.

“Contagiousness” refers to how easily the spread of an infectious disease is possible from one person to another. Words like, “infectious”, “communicable” and “transmission” are related to the word “contagious”. Genetic inheritance and contagion is not the same thing. One is born with genes in DNA so they cannot be transferred.

Genetic conditions are inherited from parents, and one has them from birth so a genetic condition cannot be acquired after birth. Contagiousness is the transfer of an infectious agent like virus or bacteria between people. Some diseases that are contagious are;

  • Viruses- common cold and flu
  • Bacterial diseases
  • Fungal conditions
  • Prion diseases- Transfer of infectious proteins is possible for this rare type of disease by direct exposure to brain tissues eg. Performing brain surgery or autopsy.
  • Worm conditions
  • Parasitic conditions

Some non-contagious diseases are;

  • Genetic diseases- One is born with a DNA so cannot catch a bad DNA from another person except from parents.
  • Cancers- they are not contagious unless there is an infected organ transplant.
  • Mental conditions- One cannot catch a depression or anxiety disorders.
  • Malnutrition disorders- Disease caused by a dietary deficiency
  • Hormonal conditions

Seborrheic keratosis is not contagious, do not spread and cannot turn into cancerous tumors. In actual fact they are rarely dangerous. They can even be left without treatment or removal. Therefore they do not threaten one’s health though they can be irritating or cosmetically displeasing. One can take into consideration some methods of treatments like;

–      Medically approved cryosurgery process which is done by freezing with liquid nitrogen.

–      Ablation which is done by vaporizing the skin growth with a laser.

–      Electrocautery which requires burning the skin growth with an electric current.

–      Application of creams containing ingredients like grape seed oil and avocado oil.

–      Applying some amount of hydrogen peroxide to the affected areas.

–      Applying natural herbal creams like sebaton, keratosis, etc.

Once again, seborrheic keratosis is thought by experts to be hereditary so they cannot be or are not contagious.
