I'm a 13 year old girl and I am showing basically every symptom of throat/oral cancer.I have a visible lump at the back of my throat,my tonsils look strange,the insides of my cheeks seem thicker than usual,I've had a cough for nearly a month,I'm dizzy whenever I stand up or cough and I think I've lost weight.Im constantly clearing my throat too.My family all smoke so I feel like inhaling the smoke could have an impact on this.My mum is insisting that I'm fine but I'm terrified and she won't take me to the doctors.I am scared that it's too late and I'm fearing the worst.Someone please reply as soon as possible,I don't know what to do and I'm so so scared.
