Liver cancer – Silent signs and risk factors

Liver cancer, known to be one of the fastest-growing types of cancer, is a life-threatening health condition. There are two types of liver cancer: primary and secondary. Primary liver cancer begins in the cells or bile ducts, whereas secondary cancer spreads to the liver from other parts of the body. In either case, the symptoms usually don’t appear until the advanced stages. Here are some of the silent signs of liver cancer: causes, diagnosis, and management options.

Silent signs of liver cancer
Liver cancer is often referred to as a silent condition because it is quite challenging to detect in the early stages. As the cancer progresses, some of these symptoms begin to show up.

  • Unusual swelling and pain in the abdomen
    In most cases of liver cancer, constant pain starts to develop in the upper right region of the abdomen. In addition, there is considerable swelling. Those who are asymptomatic may experience stabbing pain when the area over the liver is pressed slightly during a physical examination. However, these symptoms do not necessarily indicate liver cancer. It may also happen due to other health conditions, such as issues with the pancreas or gallbladder or due to a hepatitis infection.
  • Loss of appetite
    A loss of appetite can happen due to different health conditions, including cancer and viral infections. However, if it occurs along with other known signs of lung cancer, one must consult their doctor. Those with high-risk factors need to undergo liver cancer screening.
  • Feel full quickly
    As the cancer cells start to multiply rapidly, liver cancer starts to affect the digestive system. There can be an excess accumulation of fluids in the abdomen. As a result, one may feel full very quickly, even after eating just a little. Furthermore, one may also experience other symptoms, such as nausea and burping, which may lead to unconsciously reducing portion sizes for meals.
  • Significant changes in bowel movements
    Liver cancer can drastically change one’s bowel movements. As the cancer advances, the tumors begin to grow and spread. This has an impact on the bowels. Sometimes, food remains undigested and is not absorbed by the digestive system. This food passes through the bowels, making diarrhea a common occurrence. However, diarrhea as a standalone symptom cannot be considered an indication of liver disease. It can also occur due to other preexisting conditions such as Crohn’s disease, irritable bowel syndrome, GERD, or Celiac disease.
  • Yellowish tinge to the skin and eyes
    Eyes and skin turning yellow are usually signs of jaundice. However, it can also indicate liver cancer. In such cases, this symptom is often accompanied by relentless itching sensations.Other common symptoms of liver cancer include weakness and tiredness, persistent pain in the right shoulder, and frequent occurrences of a fever.

Risk factors
Liver cancer is a rare health disorder. Since most of its symptoms occur later, it helps to undergo regular screening if one is at a higher risk. Here are a few factors that increase the probability of liver cancer: Being aware of these common risk factors may help in seeking an early diagnosis.

  • Chronic infection with HBV or HCV
    Those who have a chronic infection with the hepatitis B virus (HBV) or hepatitis C virus (HCV) are at a higher risk of developing liver cancer.
  • Cirrhosis
    An irreversible and progressive condition, cirrhosis causes the formation of scar tissues in the liver. It is a significant risk factor for liver cancer.
  • Inherited liver diseases and diabetes
    Certain liver diseases, such as hemochromatosis and Wilson’s disease, that are genetic and inherited, increase the risk of liver cancer. Additionally, a person with pre-existing diabetes needs to undergo regular screening since the risk of liver cancer is significant in such cases.
  • Nonalcoholic fatty liver disease
    When there is a high accumulation of fats in the liver, it leads to the development of fatty liver disease. It increases the probability of having liver cancer as well. An accumulation of fat in the liver increases the risk of liver cancer.
  • Exposure to aflatoxins
    Those who have had prolonged exposure to aflatoxins may develop liver cancer over time. Aflatoxins are poisonous compounds released by mold growing over poorly stocked crops such as nuts and grains.

Diagnosis
When a person with high-risk factors starts exhibiting some of the silent signs of liver cancer, a healthcare provider will start with a series of physical examinations. They will ask questions regarding the family history of medical conditions and a person’s medical history. Once these are done, some or all of these tests may be recommended to get an accurate prognosis for liver cancer.

  • Blood tests
    These tests include liver function tests that check the liver enzymes, proteins, and other substances. These are checked for indicators showing whether the liver is damaged or healthy. Some blood tests also check for AFP, or alpha-fetoprotein. A high AFP count may be indicative of liver cancer.
  • Ultrasound
    Sonography images show the structures of soft tissues in the abdomen and the near arrears, including the liver. If a tumor is growing in the liver, it will be visible through this test.
  • Computed tomography (CT) scan
    This is an X-ray-based imaging test that is useful in ascertaining the location and size of a tumor that is growing due to liver cancer.
  • Magnetic resonance imaging (MRI)
    This imaging test uses radio waves to check whether the cancer has spread to other parts of the body.
  • Angiogram
    Dye is injected into the artery to look for blockages such as tumors and blood vessel activity in the liver. Angiograms help to determine the extent to which cancer has spread in the liver.
  • Biopsy
    This is a minor surgical process that involves removing some liver tissue. The tissue is then studied under a microscope to check for the presence of cancerous cells. This is one of the most reliable ways to confirm a liver cancer diagnosis.

Top 6 foods that may reduce dementia risk

Top 6 foods that may reduce dementia risk

Many individuals mistakenly believe that dementia is a disease, but it’s a term used to describe symptoms related to memory, social abilities, and thinking. These symptoms can be challenging to manage and can impact daily activities. However, healthcare professionals often recommend implementing a healthy meal plan as a way to improve management. If you’re interested in learning about how your food intake can reduce the risk of developing dementia, read on. What is dementia? As previously mentioned, dementia is not a specific disease. Instead, health conditions like Alzheimer’s disease are among its most frequent causes in older adults. Other known causes of dementia include damage to the blood vessels that supply nutrients to the brain, the formation of balloon-like proteins in the brain, and the breakdown of connections and nerve cells in the brain. While memory loss is one of its most recognizable signs, this symptom alone does not mean one has dementia. Most symptoms of this group of health issues can vary depending on the cause. Hence, here are some of the most common signs to look out for. Memory loss Difficulties while communicating Reasoning and problem-solving issues Poor control of movements and coordination Disorientation Confusion What are the foods that can help reduce the risk of dementia? Typically, dementia and Alzheimer’s are known to be caused by a combination of several factors, such as environmental, lifestyle, and genetic. Furthermore, developing issues such as high blood pressure, diabetes, and heart disease can contribute to cognitive decline in patients. Therefore, healthcare professionals suggest the consumption of nutrient-rich foods to reduce dementia risk as one grows older. Some of the foods that can be added to one’s meal plan are: Avocados Avocados are one of the most commonly known superfoods, which can provide the brain with the needed energy without a spike in blood sugar levels.
Avoid these 15 common shower mistakes

Avoid these 15 common shower mistakes

There is nothing a warm shower cannot resolve. Showering after a long day can be a stress reliever and enhance one’s mood instantly. It also has several other health benefits besides cleansing the body, including facilitating cold relief, boosting immunity, and relieving muscle pain. However, not bathing the right way can give rise to skin conditions such as rashes and eczema. Here are some common mistakes one should avoid while bathing and showering: Not moisturizing after a shower Wiping after a bath can reduce the body’s moisture, causing dry skin, which can lead to rashes and itching. Dermatologists recommend applying body lotion and moisturizer immediately after a shower to retain skin texture and prevent dryness. One should look for hypoallergenic moisturizers that do not have any added fragrances. Bathing in scorching hot water Scorching hot water can damage keratin cells in the skin’s outer layer. Consequently, the skin becomes dry and dehydrated. It is important to balance the water temperature before stepping into the shower. Ideally, the temperature of the water should be lukewarm. Using the wrong towel An absorbent towel that does not feel rough is ideal for wiping oneself after a shower. The most effective way to select the right towel is to check its density, measured in grams per square meter (GSM). Towels with GSMs between 400 and 550 are considered ideal for use after bathing. One should avoid towels below a GSM of 400, as these towels can be thin and rough, causing skin dryness. Moreover, towels made of superior-quality Egyptian or Turkish cotton are extremely soft and perfect for the skin. Soaping the arms and legs excessively While it is important to wash and clean one’s arms and legs, these areas typically do not collect much oil and dust. Hence, scrubbing them excessively can dry out these areas and hamper their natural texture.
15 signs of a weak immune system

15 signs of a weak immune system

The immune system is a complex network of organs, cells, and proteins that act as the body’s defense mechanism against diseases and infections. The system —the innate immune system that people are born with and the adaptive immune system, which develops due to exposure to toxins and microbes. Both parts work together to keep infection-causing germs and toxins. So, weak immunity can make the body susceptible to diseases and other health issues. High stress levels The American Psychological Association suggests that chronic stress weakens the immune system. This is because stress lowers the number of white blood cells (i.e., lymphocytes) in the body that fight infections, increasing the risk of infections such as the common cold. Persistent cold Most adults develop two to three colds per year, which usually last from 7 to 10 days. During this period, the immune system forms antibodies to fight the virus. However, if one keeps catching a cold or is dealing with common cold symptoms for a long time, it could be a sign of weak immunity. Slow-healing wounds When one develops a cut or a wound, the body immediately goes into damage control mode to stop any bleeding and regenerate skin. Immune cells in the body guide this process. However, when dealing with a weakened immune system, wounds take longer to heal. This can make one more susceptible to infections as well. Frequent infections Those with a lowered immunity are at a higher risk of contracting infections such as pneumonia, meningitis, bronchitis, and skin infections. They are also more likely to experience autoimmune disorders, organ inflammation, blood disorders such as anemia, and growth and developmental delays. According to the American Academy of Allergy, Asthma, and Immunology, some signs of weak immunity include: – Having more than four ear infections in a year – Developing pneumonia twice within a year – Dealing with chronic sinusitis or more than three episodes of bacterial sinusitis in a year Fatigue If one constantly feels tired despite getting enough sleep, it may be a sign of weak immunity.
