Febrile Neutropenia

Whole Body Reaction to Infection

Ryan completed chemotherapy cycle 4 in March 2017. We were discharged from the Teenage Cancer Trust ward at Cardiff hospital and managed a week at home before Ryan was unfortunately admitted to Carmarthen hospital with febrile neutropenia.

Febrile neutropenia is a whole-body reaction to infection when there is a low immunity due to chemotherapy. Ryan's temperature reached 40.1C and his lymphocyte white blood cell count was 0.2. When the count falls below 1, this is called neutropenia and infections become a high risk.

Neutropenia is very common in cancer patients and we have done well to avoid an episode up to this stage. The standard oncology protocol is to spend a minimum of 48 hours on IV antibiotics and 7-10 days on growth hormone injections to support the recovery of the white blood cell count. It didn’t go quite as smoothly as this however for Ryan, but that is whole other story that will be told later. Chemotherapy is likely to cause a low white cell count - particularly neutropenia.  If you or a patient you care for presents with any form of infection while undergoing chemotherapy treatment it is urgent they receive the same day full blood count and that you know to look out for the following: If neutrophils <1.0 and the patient is febrile (>38C on one occasion or >37.5C on two occasions taken half an hour apart), admission to hospital is required for IV antibiotics. If neutrophils >1.0 and the patient is febrile but well, consider oral antibiotics after checking with GP/Local Hospital/Oncology team. If neutrophils are >1.0 and the patient is febrile and clinically unwell please liaise with your emergency contact team. If you are ever unsure. Get checked. It is the age-old ‘better to be safe than sorry’ scenario. Chemotherapy is well known to lower your resistance to infections. When you have lower than normal white blood cells your body is less able to fight infections. When you are neutropenic it is strongly recommended to not spend long periods of time in crowded places, such as cinemas, shopping centres, swimming pools etc. It is also sensible to avoid close contact with any family or friends who have obvious coughs, colds, flu etc. You should take it very seriously if you do develop an infection whilst on chemotherapy and for up to four weeks after treatment. Signs of an infection are: A temperature above 38C on one occasion or above 37.5C on two occasions during a half-hour period. A sore throat. A chesty cough. An upset stomach. Needing to pee more often or pain when going. Feeling generally unwell. Redness, discharge or shivery episodes after use of Hickman or other central lines. Don’t delay seeking advice and treatment. Infections are a SERIOUS risk and can become life-threatening very quickly if ignored. Fortunately, Ryan recovered well from this latest blip and we put it down as just another bump on our badly paved trip, down Lymphoma Road.


  1. You depth of medical knowledge continues to astound me xxxx

    1. Thank you for your kind words. I have learned a great deal over the last year. I wish biology had been this interesting in school. Wait till to read our post on his Adrenal Insufficiency coming soon. x

Missing Education due to Illness

The Importance of Attendance If you read any news articles on education, correspondence from your child’s school, or are simply clued up on parenting then you will know the importance of school attendance. Schools place a great deal of focus on targets and will often offer incentives and competitions to encourage and increase attendance figures, but what if your child has a serious illness. What happens if they really are not well enough to attend school. What happens then? Attendance targets at Ryan's school are currently set at 95% attendance for the school year. Therefore realistically your child can only miss 10 school days due to illness. Medical appointments such as GP or Dentist do not count, but you are encouraged to make these appointments outside of the school day where feasibly possible. If your child consistently misses school, even if it is only one day a week, that equates to 39 days over the school year. Even missing one day in a week results in pressure on the

Questions to ask after Cancer diagnosis

Cancer Sucks I have shared with you Ryan's lymphoma journey where we have talked about the ups, the downs, the protocols for drugs, the side effects, but I realised recently I have never shared the questions. This post is all about what to ask when you receive a diagnosis of cancer. Receiving a cancer diagnosis is never ever going to be seen as good news. It can never be dressed up or made pretty. It is devastating, it is gut-wrenching, it is life-changing. There is so much information to process you will not think of the questions you need to ask or you will have hundreds of questions you want to ask all at once. These are just some of the questions you can ask once you have processed the news, in order to gain a better understanding of your fight ahead. General Information What type of cancer do I have? Where is it located? What are the risk factors for this disease? Is this type of cancer caused by genetic factors? Are other members of my family at risk? What lifestyle c

3 Years in Remission

  3 Years in Remission In May 2017 Ryan finished his 6 gruelling cycles of Chemotherapy and was in remission for 3 months before his cancer returned in September 2017. I wrote about our first 3 month cancer free milestone in our blog post here . In August 2020 Ryan once again finished treatment. This time he completed 3 years of Immunotherapy treatment and in November 2020 Ryan had tests done to confirm he is once again in remission. This is, of course, outstanding news but we were muted in any celebrations as it was such early days and we had been here once before. Ryan has been having regular check-ups every 3 months and in May 2021 we were able to confirm he has reached the 9-month milestone which was phenomenal news. Massive Scare - Relapse #3, ALMOST. Tuesday 4 October 2022. Ryan mentioned to me about an Ulcer on the roof of his mouth. I took photos and monitored for a couple of weeks before we start to panic too much.😳 Thursday 27 October 2022. Sadly Ryan has had to have yet a

Swansea Community Farm

Swansea Community Farm In April 2021 Ryan began volunteering at Swansea Community Farm (Welsh - Fferm Gymunedol Abertawe). For now, he attends one day a week on a Tuesday from 10 am to 4 pm but there is a possibility that he could also volunteer on Thursdays as well also 10 am to 4 pm. About the Farm Swansea Community Farm is the only city farm in Wales set in 3.5 acres of land with a variety of animals, an allotment, wildlife habitats, beehives and a café. The animals include donkeys, goats, sheep, ducks, geese and chickens. The farm aims to improve wellbeing, build skills and create a sense of community engagement by caring for the animals, producing local food and caring for the local environment. Duties Ryan has enjoyed a variety of different duties so far. He has walked the Donkeys, Sheep and Geese from their barns out to their fields and pond. Collected eggs from the Chickens, and has mucked out the donkey sheds. He has also cleaned out the chicken coops, cleaned and refilled all


By Ryan I like photos. Well the detail and how realistic you can get them. Instead of going out and looking at them yourself you can easily just find them, but doing photography you do that yourself. In a good picture I look for detail and how good it looks, which comes under detail actually, lighting, depth, what’s in the background, what’s the main focus of the picture that type of stuff. Possibly my autism has helped me to see the detail in making a good photograph. I looked at it a bit more. I can see deeper into the picture. I get the meaning of it. I can see why somebody took it either for the beauty of it or just for fun maybe. With my photography I am not having to interact with people or do the social thing that I find difficult. It’s a project I can do by myself in my own time.  My photos don’t involve people. I prefer wildlife and landscape photography instead. I don’t take photos of animals even though I like them because well fi
