Cancer biomarkers

Cancer biomarkers are special substances that can be found in blood, urine, or tissues.

They act like warning signals, helping doctors to detect, monitor, and follow up certain cancers.

Biomarkers alone can’t confirm cancer, but they give important clues that guide further tests and treatment.

Common Cancer Biomarkers and Their Uses:

◆ Thyroid: CEA, Thyroglobulin → used to check for recurrence after treatment.

◆ Lung: CEA, CA-125, Cyfra 21-1 + help in detection and follow-up.

◆ Breast (female): CEA, CA 15-3 → often used to monitor response to treatment.

◆ Liver/Bile Duct: CEA, AFP, CA 19-9 + AFP is key for liver cancer, CA 19-9 for bile duct cancers.

◆ Oesophagus: CEA, CSS + may help in detecting progression.

◆ Stomach & Pancreas: CEA, CA 19-9, CA 72-4 + commonly checked in pancreatic and gastric cancers.

◆ Colorectal: CEA, CA 19-9, M2-PK + especially useful in follow-up after treatment.

◆ Ovaries (female): CA-125, CA 72-4+ CA-125 is one of the most widely used tumor markers in gynecology.

◆ Uterus (female): CEA, CA-125, SCC → useful in tracking disease activity.

◆ Prostate (male): PSA, FPSA & ratio + PSA is a key marker for early detection and monitoring ◆ Testicle (male): AFP, β-hCG + very important in diagnosis and monitoring.

◆ Bone metastasis: CEA + may indicate cancer spread to bone.

Important Note:

High biomarker levels don’t always mean cancer they guide doctors to do more tests.

These tests help with early detection and monitoring during treatment.

Early action and regular checkups can save lives.

Awareness leads to early detection. Let’s spread the knowledge and fight cancer together.

Vitiligo

Understanding the Different Types of Vitiligo.

The Autoimmune Disorder That Attacks the Skin.

Most people understand that vitiligo is a disease that causes patches of white or lighter-toned skin to form. This happens because the immune system incorrectly identifies pigment-creating cells called melanocytes as harmful foreign bodies. 

The immune system then activates, attacking and destroying these skin cells and stripping the skin of its pigment.

Because vitiligo is a malfunction of the immune system, patients with this skin disorder are more likely to develop other autoimmune conditions like:

Addison’s disease

anemia

lupus

psoriasis

thyroid disease 

rheumatoid arthritis

inflammatory bowel disease 

systemic lupus erythematosus 

type 1 diabetes mellitus 

While vitiligo affects people of all ethnic and racial backgrounds, it is typically more visible on darker skin tones. This is why it is most commonly associated with people of color, particularly those with African or Middle Eastern backgrounds. Most commonly pigment loss begins on the hands, arms, feet, or face, but these aren’t the only areas vitiligo can affect.

The 7 Types of Vitiligo

Most people have no idea that vitiligo is an umbrella term that includes 7 subtypes of the autoimmune disorder. 

They are:

Generalized Vitiligo: This is the most common type of vitiligo, generalized vitiligo causes macules (small clusters of pigment loss) to appear in various places on your body.

Segmental Vitiligo: This type of vitiligo is more regional, affecting one side or one area of the body, such as your hands or face.

Mucosal Vitiligo: Mucosal vitiligo may be less immediately apparent because it affects the mucous membranes of your mouth and/or genitals.

Focal Vitiligo: Focal vitiligo is rare and manifests as centralized macules in a small area that don’t spread within one to two years.

Trichome Vitiligo: This type causes a bullseye pattern to form on the skin: a white or colorless center, then an area of lighter pigmentation, and an area of your natural skin tone.

Universal Vitiligo: This rare type of vitiligo causes more than 80% of your skin not to have pigment. It is not the same thing as albinism, which affects the body’s melanin production rather than destroying melanin-producing cells.

Vitiligo Treatments and Prevention

As a genetic condition that may be hereditary, there is no current preventative treatment for vitiligo. If your family has a history of vitiligo, however, these lifestyle changes may help to prevent significant pigment loss:

Use sunscreen and protective clothing to prevent sun damage.

Never use a tanning bed or sunlamp.

Try to avoid skin injuries like cuts, scrapes, and burns.

Consider taking immune-supportive supplements.

Eat a balanced, nutritious diet and minimize stress.

Treatments can help slow or reduce its spread and may assist with pigment restoration. 

Medications like Corticosteroids, JAK inhibitors, and certain creams and topical ointments may effectively reduce the appearance of white or lighter-toned patches. 

However, it’s important to note that results take time and, as an autoimmune response, vitiligo can be resistant to treatment. 

Patience is key for attaining long-term results. In the meantime, cosmetic products and self-tanning lotions may help to conceal affected areas and provide a more even-looking complexion.
