The refrigerator should also be cleaned periodically.
If mold develops on food, discard it safely and clean the affected area.
The FDA recommends discarding moldy food and following proper refrigeration and food-handling practices.
The mistake of blaming one food for every illness
When two members of the same family develop liver cancer, it is natural to search for one shared explanation.
However, cancer does not usually have one simple cause.
Aflatoxin exposure is a recognized risk factor, but it is only one part of the larger picture.
Chronic hepatitis B and C infections, cirrhosis, alcohol use, obesity, diabetes, and metabolic liver disease are also important factors.
For some people, several risk factors may work together.
For example, someone with chronic hepatitis B who is repeatedly exposed to aflatoxin may face a greater risk than someone exposed to either factor alone.
This is why doctors must examine the entire medical history.
They may investigate whether the couple has chronic viral hepatitis, assess liver function, review alcohol consumption, and examine other metabolic and environmental factors.
A refrigerator inspection alone cannot explain why two people developed liver cancer.
The purpose of food safety is to reduce avoidable exposure, not to create fear around every ingredient in the kitchen.
Families should discard clearly spoiled food, purchase products from reliable sources, and maintain appropriate storage conditions.
These habits are practical, achievable, and beneficial for everyone.
Chapter 4: The Other Major Causes of Liver Cancer That Couples Should Never Ignore
Although contaminated food deserves attention, aflatoxin is not the only major cause of liver cancer.
In fact, chronic viral hepatitis is among the most important risk factors worldwide.
When a husband and wife receive similar diagnoses, investigating hepatitis B and hepatitis C may be just as important as reviewing their dietary habits.
Understanding these conditions can help families take practical steps to protect their health.
1. Chronic hepatitis B infection
Hepatitis B is a viral infection that affects the liver.
Some people recover from the initial infection, while others develop a chronic infection that can persist for many years.
Chronic hepatitis B can cause ongoing inflammation and liver damage.
Over time, some patients develop cirrhosis, a condition in which healthy liver tissue is replaced by scar tissue.
This increases the risk of developing liver cancer.
One important characteristic of hepatitis B is that it can spread through infected blood and certain body fluids.
Transmission can occur through:
-
Sexual contact without appropriate protection.
-
Sharing needles or contaminated injection equipment.
-
Exposure to infected blood.
-
Transmission from an infected mother to her baby during childbirth.
Because spouses share intimate contact, both partners may need testing if one is diagnosed with chronic hepatitis B.
However, a positive test does not establish when or from whom the infection was acquired.
Some people carry hepatitis B for decades without knowing they are infected.
This is why testing is important even when a person feels completely healthy.
Vaccination is one of the most effective ways to prevent hepatitis B infection.
People who are not immune should discuss vaccination with their healthcare providers.
2. Hepatitis C infection
Hepatitis C is another viral infection that can cause chronic liver disease.
Unlike hepatitis B, there is currently no widely available vaccine against hepatitis C.
The virus is primarily transmitted through exposure to infected blood.
Sharing contaminated needles or inadequately sterilized medical equipment can create a risk.
Many people with hepatitis C have no noticeable symptoms for years.
However, chronic infection can gradually damage the liver and lead to cirrhosis.
Modern antiviral medications can cure most hepatitis C infections.
This makes testing particularly important for people who may have been exposed.
3. Excessive alcohol consumption
Long-term heavy alcohol consumption can damage liver cells.
Repeated injury may cause inflammation, fatty changes, and eventually cirrhosis.
People with cirrhosis have a substantially increased risk of liver cancer.
If both spouses regularly consume large amounts of alcohol, they may share this risk factor.
Reducing alcohol consumption or avoiding alcohol altogether can help lower certain liver-related health risks.
4. Fatty liver disease and metabolic problems
Fatty liver disease occurs when excessive fat accumulates in liver cells.
The condition is increasingly associated with obesity, insulin resistance, type 2 diabetes, and metabolic abnormalities.
The current medical term for metabolic dysfunction-associated fatty liver disease is MASLD.
Some patients develop inflammation and progressive liver scarring.
In advanced cases, this can lead to cirrhosis and increase the risk of liver cancer.
People with diabetes, obesity, or metabolic syndrome should discuss appropriate liver health assessments with their healthcare providers.
5. Smoking
Smoking is associated with an increased risk of several cancers, including liver cancer.
Tobacco smoke contains numerous harmful chemicals that can contribute to cellular damage.
Quitting smoking is an important step toward improving long-term health.
6. Family history and certain inherited conditions
Some rare inherited conditions can increase the likelihood of developing liver disease.
These include hereditary hemochromatosis, a condition in which the body absorbs and stores excessive iron.
Wilson disease and certain inherited metabolic disorders can also affect the liver.
A family history of liver disease may therefore be relevant when doctors assess a patient's risk.
The National Cancer Institute and American Cancer Society identify chronic viral hepatitis, cirrhosis, alcohol, metabolic conditions, and aflatoxin exposure among the important risk factors for liver cancer.

What should couples do after one partner receives a diagnosis?
If one spouse is diagnosed with liver cancer, the other should not assume they will develop the same disease.
However, it is sensible to discuss shared risk factors with a doctor.
Depending on the medical history, the healthcare professional may recommend:
-
Hepatitis B testing.
-
Hepatitis C testing.
-
Hepatitis B vaccination if appropriate.
-
Assessment of liver function.
-
Evaluation of metabolic risk factors.
-
Further liver imaging when clinically indicated.
