Breast cancer is indicative of smelly armpits. Reasons for a person to occasionally smell Of course, bad personal hygiene comes first. specific medical treatments, such antidepressants. Probably hormonal and odd; maybe it will pass quickly. being too fat.

If you’re wondering why only one armpit smells like cancer, the problem may be as easy as using antiperspirants or deodorants wrong. Often, this is caused by forgetting to cover both armpits, so it’s imperative to use the right ones.


Various possible causes of moisture in armpits include certain medical conditions, food allergies, and bacterial infections. Doctors may recommend a specific type of antiperspirant or other treatment for those who feel their armpits smell. However, prevention is better than cure, so you should avoid food and drink that trigger excessive sweating and keep the area dry and clean.

Armpit smell is caused by a bacterium that lives inside the armpits and mixes with an odorless molecule in sweat. When this combination is present, it interacts with the active microbiota inside the follicles to produce a distinctive body odor.

Different kinds of bacteria can cause armpit odors, and you should wash your workout clothes right after each workout. Benzoyl peroxide can help kill bacteria that cause armpit odor. However, it would help if you remembered that this harsh chemical could cause a stinging sensation. In addition, you should shave your underarms frequently to minimize moisture.

Using antiperspirants and deodorants will help you control the odor. These products block the sweat pores temporarily, which leads to a reduction in armpit odor. Depending on the cause, you can also try Botox injections to help with the problem. Good hygiene, shaving, and wearing loose-fitting clothes are also essential steps.

Using antibacterial soap to wash your armpits can help reduce bacteria in the area. Using deodorant will also reduce the amount of sweat in your armpits. Additionally, shaving your underarms will help you keep your armpits smelling clean. Lastly, it would help if you tried to avoid wearing soiled clothes and wash your laundry regularly.


If you think only one armpit smells, you may be experiencing a cancer-related odor. Odor in the armpits is caused by a mixture of good and bad bacteria. When this balance is upset, the harmful bacteria overgrow, making the armpit smell more noxious. Therefore, if only one armpit smells, you should take steps to improve the balance.

The underlying causes of body odor are still unknown, but researchers have linked specific genetic changes to the occurrence of body odor. People with the mutation ABCC11 have a deficiency in a protein that transports molecules across cellular membranes. This mutation worsens the armpit smell because it prevents the armpit bacteria from metabolizing sweat compounds. This mutation is expected in the East Asian population.

The discovery could lead to practical tools for clinical practitioners using genetic testing to predict breast cancer risk. Currently, there is no definitive test for breast cancer, but this research could give doctors a better idea of what to look for in a patient. For example, a patient who develops breast cancer may also exhibit malodor.

Eccrine glands

The leading cause of body odor is sweat, which mixes with bacteria. Sweat glands are located in the armpits and groin areas of the body. This fluid is transparent and smells foul. Bacteria and other waste products build up in the sweat glands and cause a foul odor.

Most people have a range of different odor-causing bacteria in their armpits. One of these is Staphylococcus hominins. It produces thioalcohol, the most aromatic compound in body odor. It does this by converting odor-less precursor molecules into pungent-smelling compounds.

However, the odor produced by the body varies from person to person. It is also influenced by genetics. Some populations have a gene mutation that prevents them from secreting thioalcohol. Scientists say that body odor is more than just bacteria. It may even go beyond what the human nose can detect.

A simple solution to this problem is to apply deodorant or antiperspirants to both armpits. The difference in odor is caused by disrupting the average balance of good and bad bacteria. When the balance is upset, the harmful bacteria overgrow and intensify body odor.

Staphylococcus hominis

The bacteria Staphylococcus hominis produces a pungent odor in the sweat glands. This chemical is produced by an enzyme produced by the bacterium and is derived from the thioalcohol Cys-Gly-3M3SH. The bacteria are closely related to Staphylococcus aureus, which also produces a foul odor.

Staphylococcus hominis is part of the natural microbiome in the armpits. The bacteria produce the body odor as an end product of the digestion of odorless sweat molecules. These bacteria were present in human armpit microbiomes long before the evolution of Homo sapiens and may have played an important role in societal communication between ancestors.

The researchers found that those individuals with higher odors had more Corynebacterium. Of these, OTU470219 was the most common. In contrast, those with lower odors had more P. acnes. The study also showed a strong positive correlation between two or more bacteria.

The data set also contains 68 genera. Most belong to the Firmicutes and Actinobacteria, the bacterial group responsible for human axillary odor. These bacteria are also responsible for the sour smell in children and teenagers.


If you can smell the odor of cancer only under one armpit, you’re not alone. According to dermatologist Marisa Garshick, a professor of dermatology at Cornell-New York Presbyterian Medical Center, another armpit may smell more than the other. A variety of factors can cause this. In some cases, the odor is due to an infection or a problem with the apocrine glands, the glands that produce body odor.

In most people, around 100 to 200 different types of bacteria live in their armpits. One of them, Staphylococcus hominis, is responsible for body odor. It produces the compound thioalcohol, considered the most aromatic component of body odor.

Scent research is a promising area for cancer diagnosis, but it’s still a developing field. Unfortunately, there is no universal method of detecting cancer by scent, so no one can reliably identify a tumor by its smell. But there are some common cancer symptoms, such as an odor associated with an ulcerating tumor. However, this odor could result from a wound or dead tissue bacteria.

Researchers have found a genetic mutation that may be responsible for the characteristic odor of one armpit. This mutation affects the secretion of thioalcohol, which is the smell that makes one armpit smell so bad. However, there are ways to treat the problem, including the underlying cause.
