Amyloidosis: when light chains damage organs | CION Cancer Clinics
AL amyloidosis happens when abnormal light chains build up as amyloid in organs such as the heart, kidneys and nerves. Early symptoms are vague: breathlessness, swollen legs, frothy urine, tingling feet or weight loss. Diagnosis needs light chain tests and a tissue sample that confirms the type. This page explains the symptoms, the tests, and when not to wait. At CION Cancer Clinics, our haematology team plans myeloma and lymphoma care with you, discussed at a tumour board and explained in plain words.

The short answer
What is AL amyloidosis, and how would you notice it?
AL amyloidosis happens when abnormal light chains fold into a stiff protein called amyloid and build up in organs such as the heart, kidneys and nerves. Its symptoms are vague at first, like breathlessness, swollen legs, frothy urine or tingling feet, so it is often found late.
How it links to MGUS and myeloma
The light chains come from a small group of abnormal plasma cells, the same kind of cells involved in MGUS and myeloma. In AL amyloidosis the number of these cells is often small. The harm comes from where the protein settles, not from the cells crowding the bone marrow.
Why it is easy to miss
Each symptom points to a common problem. Breathlessness looks like heart failure from blood pressure. Protein in the urine looks like diabetic kidney disease. Tingling looks like a vitamin deficiency. Doctors start to suspect amyloidosis when several organs are affected together, or when the usual explanation does not fit.
Who should think about it
Anyone with known MGUS or an abnormal light chain ratio who develops new symptoms in more than one organ should mention the MGUS to every doctor they see. That single sentence can shorten the path to diagnosis.
AL is one type of amyloidosis. Other types have different causes and treatments, which is why the exact type must be confirmed.Symptoms by organ
Which symptoms can AL amyloidosis cause?
Symptoms depend on which organs are involved. Most of them have more common causes, so a list like this is not a diagnosis.
Heart
The heart muscle stiffens and cannot fill properly.
- Breathlessness on walking or lying flat
- Swollen ankles and legs
- Dizziness or fainting when standing up
Kidneys
Protein leaks from damaged kidney filters.
- Frothy urine
- Swelling around the eyes, legs or tummy
- Kidney function slowly falling
Nerves
Deposits affect the nerves to the limbs and to the automatic functions of the body.
- Numbness or tingling in the hands and feet
- Carpal tunnel symptoms in both wrists
- Alternating loose motions and constipation
Other signs
Some signs are less common but more specific to amyloidosis.
- An enlarged tongue with tooth marks on its edges
- Easy bruising around the eyes
- Weight loss and tiredness without a reason

When not to wait for an appointment
If you or your parent become breathless at rest, have chest pain, faint, or pass very little urine over a day, go to the nearest emergency department now or call 108. Tell the team about MGUS or suspected amyloidosis. Do not wait for the haematology clinic date, and do not change heart or water tablets on your own.
The pathway
How is AL amyloidosis diagnosed?
-
Blood and urine tests for the light chain
Serum free light chains, electrophoresis and immunofixation look for the abnormal protein. A normal result makes AL less likely but does not rule it out on its own.
-
A tissue sample
Amyloid has to be seen under the microscope. A small sample of belly fat taken with a needle is often tried first. If it is negative, a biopsy of the affected organ or the bone marrow may be needed.
-
Confirming the type
Special stains show amyloid is present. Further tests on the tissue confirm it is the light chain type and not another kind. This step matters because treatment is completely different for other types.
-
Checking each organ
Heart blood tests, an echocardiogram and sometimes a cardiac MRI show how much the heart is involved. Kidney and liver tests complete the picture.
-
A bone marrow test
This measures the plasma cells and checks for myeloma alongside the amyloidosis. The results together decide the plan.

On your report
Which words will you meet on the reports?
- Congo red stain
- A dye used on tissue that shows amyloid as a distinctive colour under polarised light.
- Fat pad aspirate
- A needle sample of fat from under the skin of the belly, used to look for amyloid.
- Typing
- Tests that confirm which protein the amyloid is made from. AL means light chain.
- NT-proBNP and troponin
- Heart blood tests. Raised levels suggest strain on the heart and help the team judge how far the heart is involved.
- Organ involvement
- Which organs show amyloid damage. It shapes both the treatment choice and how carefully it is given.
Commonly believed
What do families often misunderstand about amyloidosis?
"It is a heart or kidney disease, so the haematologist is not needed."
The organs show the damage, but the source is in the blood. Treatment targets the plasma cells making the light chain, so a haematologist leads it, working with heart and kidney specialists.
"My light chain test was normal, so it cannot be amyloidosis."
A small abnormal protein can be hard to detect. If symptoms strongly suggest amyloidosis, doctors combine several tests and may still take a tissue sample.
"Every person with MGUS will get amyloidosis."
Only a small minority do. Knowing the early symptoms lets you report them promptly, without worrying about every ache.
"Once amyloid is found, nothing can be done."
Treatment can stop more light chain being made, and organ function can steady or improve in some people. Starting before organ damage is advanced makes a real difference, which is why early diagnosis matters.
Being straight with you
How is it treated, and what can this page not tell you?
Treatment aims to switch off the plasma cells making the harmful light chain, so that no new amyloid forms. It usually uses medicines similar to those used for myeloma, such as daratumumab and bortezomib with a steroid. A small number of fit patients are offered a stem cell transplant at a specialist centre.
Who needs extra care with treatment
People with advanced heart involvement can react badly to some treatments, so the treating team adjusts the plan and its pace carefully. Supportive care for the heart, kidneys and nerves runs alongside. A transplant does not suit people whose heart or kidneys are badly affected, and your team will explain why if it is not offered.
What this page cannot tell you
It cannot tell you whether your symptoms are amyloidosis, and it cannot give an outlook. That depends mostly on how much the heart is affected and how the light chain responds, which only your team can judge.
How CION can help
CION's haematology team reviews your reports, discusses the case at a tumour board, and coordinates tissue typing, heart imaging or transplant assessment with qualified centres.
Questions we are asked
Common questions about AL amyloidosis
Is AL amyloidosis a type of cancer?
It is a plasma cell disorder, closely related to MGUS and myeloma. The abnormal cells are often few, but the protein they make damages organs. Because of this, it is treated by haematologists with medicines similar to those used for myeloma, even when there is no myeloma.
I have MGUS. How do I know if it is becoming amyloidosis?
Watch for new breathlessness, swollen legs, frothy urine, tingling in the feet or unexplained weight loss. None of these is proof, but report them rather than waiting for your next check. Your follow-up urine protein and kidney tests also help spot early change.
Why was a fat sample taken from my belly?
Amyloid often deposits in the fat under the skin even when it is causing trouble elsewhere. A needle sample from the belly is simple, done without admission and avoids a biopsy of the heart or kidney. If it does not show amyloid, a biopsy from another site may still be needed.
Can amyloid already in the organs be removed?
There is no approved treatment that reliably clears existing deposits. Once new light chain production stops, the body can slowly clear some amyloid, and organ function may improve over months. Research into drugs that remove deposits continues, but results so far are limited.
Is amyloidosis passed on in families?
AL amyloidosis is not inherited. A different type, hereditary transthyretin amyloidosis, does run in families and can look similar. That is one reason tissue typing matters. If your family has a history of heart failure or nerve problems, tell your doctor.
Can I still take my blood pressure and water tablets?
Do not stop or change them on your own. In heart amyloidosis, some usual heart medicines are poorly tolerated and your doctors may adjust them. Bring a full list of everything you take to your appointment so the team can review it with your heart findings.
Which doctors will be involved?
A haematologist usually leads, with a cardiologist, a kidney specialist and sometimes a neurologist. Ask who is coordinating your care, so results do not sit with one specialist while another waits. A shared folder of reports helps every doctor see the whole picture.
Is treatment covered by Aarogyasri or insurance?
Coverage depends on your scheme or policy and on how the treatment is given. Aarogyasri, PM-JAY, CGHS, ECHS, EHS and cashless insurance each have their own rules, and those rules change. Check the current rules, and call the helpline with your card details for help.
