When it comes to diagnosing cancer, one of the most definitive and critical tools is the biopsy. This minimally invasive procedure helps doctors determine whether a suspicious growth or lesion is cancerous and if so, what kind of cancer it is. A biopsy involves the removal of a small sample of tissue or cells from a suspicious area in the body for examination under a microscope. Doctors may recommend a biopsy when imaging tests such as X-rays, MRIs or CT scans reveal abnormal growths. While these tests can indicate the presence of a tumor, only a biopsy can confirm whether the cells are cancerous or non-cancerous. 

Types of Biopsies

Different biopsies are used depending on the location, size, and accessibility of the suspicious tissue.

• Needle Biopsies: Either a fine-needle aspiration (FNA) is used which is a thin needle that extracts fluid or cells from a lump. It is commonly used for breast, thyroid and lymph node biopsies. Or a core needle biopsy (CNB) is used which is a thicker needle used to remove a small cylinder of tissue, providing more detailed information than FNA.
• Surgical Biopsies: Removes a small portion or the entire lump or suspicious tissue.
• Endoscopic Biopsy: Performed during an endoscopy, where a flexible tube with a camera and tools is used to take tissue samples. Common for stomach, colon and lung cancers.
• Skin Biopsy: Used to examine suspicious moles, lesions or growths for melanoma or other skin cancers.
• Liquid Biopsy: A non-invasive method that detects cancer cells or DNA fragments circulating in the blood.

What Happens After a Biopsy?

The collected sample is sent to a pathology lab where a pathologist examines it under a microscope. The analysis provides crucial information like the cancer type (whether it is carcinoma, sarcoma, lymphoma or something else) and grade (the abnormality of cancer cells compared to healthy cells).

Conclusion

While the idea of a biopsy may seem intimidating, the procedure is often straightforward with minimal risks. The benefits far outweigh the temporary discomfort as a timely biopsy can lead to early diagnosis and a higher chance of successful treatment.

Turmeric, known as the “golden spice,” has been a cornerstone of traditional medicine and culinary practices for centuries. Derived from the rhizome of the Curcuma longa plant, this vibrant yellow-orange powder is more than just a kitchen staple. It owes its remarkable properties to bioactive compounds, primarily curcumin, which is renowned for its potent anti-inflammatory and antioxidant effects.

The Medical History of Turmeric

The history of turmeric dates back nearly 4,000 years, with its origins rooted in the Indian subcontinent. It has been an integral part of Ayurveda, the ancient Indian system of medicine, where it was used to treat a variety of conditions ranging from respiratory disorders to digestive issues. Traditional Chinese medicine also embraced turmeric for its ability to invigorate blood circulation and alleviate pain. In medieval Europe, turmeric was known as “Indian saffron” and was primarily used as a dye and flavoring agent. Over the centuries, its medical applications expanded as scientific communities began to uncover the mechanisms behind its healing properties.

How Turmeric is Used Today 

Today, turmeric’s role in health and wellness is more prominent than ever. It is widely used to combat inflammation, which is at the root of many chronic diseases including arthritis, heart disease, diabetes and even cancer. Turmeric is also a popular natural remedy for conditions like irritable bowel syndrome (IBS) and ulcerative colitis due to its ability to soothe the gastrointestinal tract. It is also used in skin care to reduce acne, scars and redness, thanks to its antibacterial and antioxidant qualities.

Benefits of Using Turmeric Supplements Daily

Incorporating turmeric supplements into a daily routine can yield significant health benefits. These supplements are often enriched with piperine, a compound derived from black pepper, which enhances curcumin absorption by up to 2,000%. Regular use of turmeric supplements can help reduce joint pain and stiffness in individuals with arthritis. They may also lower the risk of neurodegenerative diseases like Alzheimer’s and Parkinson’s by neutralizing oxidative stress and reducing brain inflammation. Furthermore, turmeric supports liver health by aiding in detoxification processes and protecting against liver damage. Its immune-boosting properties make it an excellent addition to a wellness regimen, especially during times of illness or high stress.

Conclusion

Turmeric is a natural powerhouse with a rich history and remarkable health benefits. From reducing inflammation to supporting overall wellness, it is a simple yet effective way to improve your health. Adding turmeric to your daily routine, whether through food or supplements, can help you take advantage of its many therapeutic properties and enhance your quality of life.

Nerve pain, also known as neuropathic pain, is one of the most complex and challenging types of pain to treat. Unlike pain caused by an injury or inflammation, nerve pain originates from the nervous system itself, often as a result of nerve damage, dysfunction. The mechanisms behind nerve pain involve abnormal processes within the nerves and the brain, leading to pain signals that can be severe, persistent and sometimes difficult to pinpoint. 

Nerve Damage and Dysfunction

Nerve pain often begins with damage to the peripheral or central nervous system, which includes the brain and spinal cord. This damage can be caused by a variety of factors, such as injury, infection, diseases like diabetes or conditions like multiple sclerosis. When nerves are damaged, they can no longer transmit signals normally. As a result, the nerves may send pain signals to the brain even in the absence of an actual injury.

Abnormal Nerve Signaling

Once nerves are damaged, they begin to malfunction and can start sending pain signals even when no external stimulus is present. The damaged nerves can generate electrical impulses on their own, without any external trigger. This results in pain sensations that occur spontaneously or in response to non-painful stimuli. When nerve fibers are repeatedly stimulated, they can become more sensitive to stimuli. In this state, even normal sensations like light touch or temperature changes can trigger pain.

Neuroinflammation

When nerves are damaged, the surrounding tissues often become inflamed. This inflammation can make the nerves more sensitive and exacerbate pain. In the case of conditions like diabetic neuropathy, where high blood sugar levels damage the blood vessels supplying the nerves, inflammation can trigger a chain of events that further sensitises the nerve fibers. Neuro inflammation can also occur in conditions like multiple sclerosis and shingles, where the immune system attacks the nerve tissues.

Changes in the Brain’s Pain Processing

Nerve pain is unique in that it not only affects the nerves but also alters how the brain processes pain. Under normal conditions, the brain interprets signals from the body, differentiating between a harmless touch and an injury. However with nerve damage, this pain processing system can go awry.

The brain may misinterpret harmless signals, leading to pain when there is no physical injury. This phenomenon is especially common in conditions like phantom limb pain, where individuals who have lost a limb still feel pain in the absent limb.

The brain can also develop a “memory” of pain. Even after the original injury has healed, the brain may continue to send pain signals, creating a cycle of chronic pain. This can make nerve pain persistent, long-lasting and difficult to treat.

Conclusion

The mechanism of nerve pain is multifaceted and involves a combination of nerve damage, abnormal signaling, neuro inflammation and changes in how the brain processes pain. These complex processes make nerve pain difficult to treat and often lead to chronic, debilitating symptoms. Understanding the mechanisms behind nerve pain is essential in developing more effective treatments. Current treatments focus on managing the symptoms by targeting the underlying nerve dysfunction and using medications that alter pain perception and prevent further nerve damage.

Jaundice is a condition that causes the skin, the whites of the eyes and mucous membranes to take on a yellowish tint. While it might seem like a superficial symptom, jaundice is often an indication of underlying issues with the liver or bile ducts.

What is Jaundice?

Jaundice occurs when there is an accumulation of bilirubin in the bloodstream. Bilirubin is a yellow compound produced during the natural breakdown of red blood cells. Normally, the liver processes bilirubin and it is excreted through bile. However, if the liver is unable to process bilirubin properly, it builds up in the body and causes the characteristic yellowing of the skin and eyes. Jaundice is not a disease itself, but rather a symptom of an underlying issue affecting the liver.

How Jaundice Affects the Liver

Several liver-related conditions can disrupt the bilirubin metabolism process and lead to jaundice. These can be categorized into three primary types based on where the problem occurs:

1. Pre-Hepatic Jaundice 

This type of jaundice occurs when the liver is functioning normally, but there is an excess of bilirubin being produced. This can happen in conditions like hemolysis, where red blood cells are destroyed faster than the liver can process them. Conditions that cause excessive breakdown of red blood cells, such as sickle cell anemia or thalassemia, can lead to increased levels of unconjugated bilirubin. In this case, the liver’s normal ability to process bilirubin can be overwhelmed, leading to jaundice.

2. Hepatic Jaundice 

Hepatic jaundice occurs when the liver itself is damaged and its ability to process bilirubin is impaired. Conditions such as hepatitis, cirrhosis or liver cancer can directly damage liver cells, disrupting the normal processing and excretion of bilirubin. When liver cells are inflamed or scarred, they are unable to conjugate bilirubin, resulting in the accumulation of unconjugated bilirubin in the bloodstream. This is the most common type of jaundice and reflects a more serious liver issue.

3. Post-Hepatic Jaundice 

Post-hepatic jaundice occurs when the problem lies in the bile ducts, which carry bile (and bilirubin) from the liver to the intestines. Conditions such as gallstones, pancreatic cancer or bile duct obstruction can block these ducts, preventing bilirubin from being excreted from the liver. As a result, bilirubin backs up into the bloodstream and causes jaundice. This type of jaundice is often accompanied by pale stools and dark urine, as the bilirubin is unable to be eliminated properly.

Causes of Liver Dysfunction Leading to Jaundice

Several conditions can lead to liver dysfunction and subsequently, jaundice:

• Hepatitis: Inflammation of the liver, commonly caused by viral infections (e.g., hepatitis B, C) or excessive alcohol consumption.
• Cirrhosis: Chronic liver scarring that impairs the liver’s ability to process bilirubin and other substances.
• Liver Cancer: Tumors in the liver that can block bile ducts or directly damage liver cells.
• Alcohol-related liver disease: Chronic alcohol abuse can lead to fatty liver, alcoholic hepatitis, and eventually cirrhosis.
• Gallstones: Hardened deposits in the gallbladder that can block bile flow and lead to post-hepatic jaundice.
• Genetic conditions: Diseases like Gilbert’s syndrome or Crigler-Najjar syndrome can affect bilirubin metabolism.

Conclusion

Jaundice is more than just a yellowing of the skin and eyes, it is a warning sign that something is wrong with the liver or bile ducts. The liver’s role in processing bilirubin is vital, and any disruption in this process, whether due to liver disease, bile duct obstruction or excessive red blood cell destruction, can lead to jaundice. Early intervention can prevent further liver damage and improve the chances of recovery.
