Total Skin Electron Beam Therapy — Treating Skin Lymphoma Across the Whole Body

You stand in a wide electron beam, not lie under a small one. The machine is set several metres back so the field covers you head to toe. You hold a set series of standing positions, so every part of the skin surface faces the beam across the cycle. The electrons stop in the skin.

This is the part that surprises most people. Radiotherapy is usually aimed at one place. Cutaneous lymphoma is different: the disease sits across the skin rather than in a single lump, so the target is the skin itself — treated as one organ, over the whole body.

Why electrons and not X-rays. Electrons are charged particles. They slow down and stop within roughly the first centimetre of tissue, and they do not carry on through the body the way X-rays do. That depth limit is the entire point of the technique. It is what allows widespread skin disease to be treated while bone marrow, lungs, heart and abdominal organs are largely spared.

Why six positions. The long-established approach uses six standing positions — facing the machine, back to it, and four angled stances — each treated with a pair of beams angled slightly up and slightly down. Half the positions are given on one day and half on the next, so a full cycle takes two treatment days. Some centres use a rotating platform instead, with the same aim: an even dose over a curved, uneven surface.

Nothing is left to chance about coverage. Small dose detectors are taped to your skin during the first sessions to measure what each region actually received, and the plan is adjusted from those readings.

Your radiotherapy is delivered at an NABH-accredited partner centre; CION Cancer Clinics coordinates your treatment plan, your oncology team and your care throughout. CION does not own or operate a linear accelerator or any other radiotherapy machine, and is not itself NABH-accredited.

Each attendance takes about 30 to 45 minutes, and you are usually treated four days a week. The course itself is either short or long depending on the dose chosen. A low-dose course runs about two to three weeks. A conventional-dose course runs about eight to ten weeks. Your team decides which, and why.

Ask which schedule is planned for you at the first consultation, because the two feel very different to live through, and the answer changes what you should arrange at home and at work.

Because the whole skin is treated, the effects show up over the whole skin. Expect redness, dryness, itching and peeling that build through the course. Most people lose scalp and body hair temporarily. Many lose nails. Sweating is often reduced for weeks. Fatigue is usual. Almost all of it settles after treatment ends.

Expected, and part of the course

• Skin redness, dryness and peeling — builds gradually and is often at its worst in the final week or two, then settles over several weeks.
• Complete but temporary hair loss — scalp and body hair. Regrowth usually begins within a few months; at higher cumulative doses some thinning can persist.
• Loss of fingernails and toenails — common, and they regrow, though it takes months. Nail shielding is used in some plans.
• Reduced sweating for weeks to months — worth planning for in Hyderabad heat. Stay out of the midday sun, keep fluids up and take cooling breaks.
• Swelling of the hands, feet and ankles — common during and shortly after the course; elevation and gentle movement help.
• Blistering in folds, on palms and on soles — these areas take dose differently. Tell your team early rather than waiting for the next review.
• Tiredness — from the treatment and from attending daily. Plan lighter weeks rather than pushing through.

Call your team the same day if

• You have a fever, or an area of skin becomes hot, spreading, painful or starts weeping pus — broken skin over a wide area can become infected, and this needs treating quickly.
• Blistering becomes extensive or the skin breaks open widely — the dressing plan and sometimes the schedule may need changing.
• You feel faint, confused or overheated and are not sweating — reduced sweating makes heat exhaustion a real risk during a Hyderabad summer.

Longer term

Skin may stay drier than before, fine surface blood vessels can become visible, and pigmentation can change in treated areas. Reduced sweating occasionally persists. A higher long-term risk of new skin cancers in treated skin is recognised in NCCN guidance for primary cutaneous lymphomas, which is why your cumulative lifetime skin dose is recorded and why skin checks continue for years. This is a risk to be aware of and monitored, not a reason on its own to decline treatment your team recommends.

Use only the moisturiser, dressing or wash your radiation team prescribes for treated skin during the course. Products that are harmless on ordinary skin can worsen a radiation reaction, so check before you apply anything, including anything herbal or home-made.

• How much of my skin is involved, and does that justify treating all of it? — this single answer decides whole-skin versus spot treatment.
• Is there any disease outside my skin on staging? — it changes whether this technique is the main treatment or one part of a plan.
• Which dose schedule are you proposing, and why that one? — ask specifically whether a low-dose course is appropriate for you.
• Will I be able to have this again if the disease returns? — the answer depends on the dose given now, so ask before the course, not after.
• Which areas will need separate boost or patch fields? — scalp, soles, perineum and skin folds are the usual ones.
• Who manages my skin during the course, and what should I put on it? — get this in writing, including what not to use.
• Can I have a written, itemised estimate? — costs quoted are indicative only, as of August 2026, and should still be given to you in writing.

• If your lesions are few and shallow rather than widespread, the treatment discussed is usually a much smaller, gentler beam — Superficial and Orthovoltage X-Ray Therapy for Skin Lesions explains that option.
• Treating the whole skin has a close cousin that treats the whole body before a transplant, for a completely different reason — see Total Body Irradiation Before a Bone Marrow Transplant.

• For very large tumours, another specialised technique deliberately treats unevenly rather than uniformly — GRID and Lattice Radiotherapy for Very Large Tumours covers it.
